# Applied Mathematics B.S.

## Information and Policies

### Introduction

Applied mathematics is a field of research specializing in the development and application of analytical and numerical tools and techniques toward the solution of complex quantitative problems in science and engineering. A Bachelor of Science (B.S.) in Applied Mathematics prepares graduates for careers in the industry (usually in research and development) or academia (either in teaching and/or in research at university or governmental laboratories or agencies). It can be a terminal degree, or prepare students for graduate school in applied mathematics or related fields.

The applied mathematics major at the University of California, Santa Cruz, provides students with a holistic training in mathematical modeling. The core of the degree program includes six courses that introduce modern analytical (and semi-analytical) techniques as well as general aspects of scientific computing. Students gain further depth or breadth by taking three (or more) electives among a large list of upper-division or graduate courses offered by applied mathematics faculty or in related subject areas. Finally, students learn to apply the techniques and tools learned through two capstone courses that focus on modeling “real- life” quantitative problems in science and engineering. In these courses, students also learn additional skills such as mathematical abstraction, critical thinking, and disciplinary communication.

The major has been designed to allow students to easily pursue an additional minor or major in an area of applications of mathematics (such as physics, astrophysics, Earth sciences, computer sciences, computer engineering, electrical engineering), and/or to pursue the 4+1 pathway into the Master of Science (M.S.) degree program in Scientific Computing and Applied Mathematics also offered by the Department of Applied Mathematics.

### Program Learning Outcomes

Recipients of a B.S. degree in applied mathematics at UC Santa Cruz are expected to have the following skills and experiences:

- To be able to take a real-life science or engineering problem, and create a mathematical model for it, under the supervision of a professor.
- To be competent with a number of analytical methods for the solution of linear algebra problems, as well as ordinary and partial differential equations.
- To be competent with constructing numerical algorithms for the solution of linear algebra problems and ordinary differential equations.
- To be competent in at least two scientific computing languages such as: Fortran, C, Python, R, Matlab, etc. and to be familiar with other computational elements such as Unix-type operating systems, the use of compilers, professional scientific computing libraries, efficient IO algorithms, data visualization tools, etc.
- To be able to analyze critically the results from the model obtained, and identify when the model is inappropriate.
- To be able to communicate clearly and coherently with professionals (orally and/or in writing), in order to: (1) understand what is needed of the mathematical model prior to the investigation; and (2) report on the results of the model after the investigation

### Getting Started in the Major: Frosh

It is recommended that high school students intending to apply to this major have completed four years of mathematics (through advanced algebra and trigonometry) and three years of science in high school. Comparable college mathematics and science courses completed at another institution also serve to properly prepare students for these majors.

This is a course-intensive and/or sequential program, and students who intend to pursue this major must begin taking classes for the major in their first year at UC Santa Cruz.

Math placement may be required for one or more of the foundational courses for this major. For more information, please review the Math Placement website.

Transfer students should declare their major in their first quarter at UC Santa Cruz. Instructions for declaring a major in Baskin Engineering are on the department's major declaration page.

### Major Qualification Policy and Declaration Process

#### Major Qualification

In order to be admitted into the applied mathematics major, students must be listed as a proposed major within the Baskin Engineering or within the Division of Physical and Biological Sciences. Please refer to Prepare to Declare a Baskin Engineering Major.

Transfers to the program should consult the Transfer Admission Screening Requirements and the Transfer Students section of the Baskin Engineering Undergraduate Affairs page.

In addition to being listed as a proposed Baskin Engineering or Physical and Biological Sciences major, admission to the applied mathematics major is based on passing the following foundational courses:

##### Foundation Courses

###### One of the following series:

Either these courses | ||

MATH 19A | Calculus for Science, Engineering, and Mathematics | 5 |

MATH 19B | Calculus for Science, Engineering, and Mathematics | 5 |

or these courses | ||

MATH 20A | Honors Calculus | 5 |

MATH 20B | Honors Calculus | 5 |

###### Plus these courses:

AM 30 | Multivariate Calculus for Engineers | 5 |

CSE 16 | Applied Discrete Mathematics | 5 |

Declaration of the major can happen no sooner than the student's second quarter, and no later than the campus deadline.

At most, one unsuccessful attempt (grade C-, D+, D, D-, F, or NP) for a foundation course is permitted.

#### Appeal Process

Denials of admission to the major may be appealed by submitting a letter to Baskin Engineering's Undergraduate Advising office, addressed to the program undergraduate director within 15 days from the date the notification was mailed. The appeal letter must describe why the prior performance is not an accurate reflection of the student's potential. Within 15 days of receipt of the appeal, the Undergraduate Advising office will notify the student and their college of the decision.

#### How to Declare a Major

There are four steps to declaring a Baskin Engineering major. For a detailed guide to this process, please consult Baskin Engineering's Declare Your Major website.

Students should start the declaration of major process by completing Step One on the BSOE "Declare Your Major" website as soon as they complete the major qualification courses or reach their declaration deadline quarter, whichever comes first.

Students petitioning when the campus declaration deadline is imminent (i.e., in their sixth quarter, for students admitted as frosh), will either be approved, denied, or provided with conditions (e.g., completion of some courses with certain grades) that will be resolved within at most one more enrolled quarter, even if they have not completed major qualification courses.

### Letter Grade Policy

Baskin Engineering requires letter grades for all courses in an engineering major.

### Course Substitution Policy

Undergraduate engineering students who wish to substitute a major course with a course from UC Santa Cruz must first consult Baskin Engineering's Undergraduate Advising Office. The advising office requires a Petition for Course Substitution be approved before credit for an alternate course can be applied to any Baskin Engineering major requirement. Petition forms are available at the undergraduate advising office and on the Baskin Engineering advising website.

Petitions and procedures for approval must be obtained from and submitted to the Undergraduate Advising Office.

### Double Majors and Major/Minor Combinations Policy

Students who are planning a double-major with physics can replace the AM 100, AM 112 and STAT 131 (or CSE 107) courses with the PHYS 116A, PHYS 116B, and PHYS 116C series. Special approval by both undergraduate directors will be required to do so.

### Honors

Students must obtain a GPA of 3.8 or higher in the courses in the major to be considered for the distinction of “Highest Honors in the Major.” Students must obtain a GPA of 3.5 or higher in the courses in the major to be considered for the distinction of “Honors in the Major.” Baskin Engineering reserves the right to withhold honors based on other criteria, such as an incident of academic dishonesty.

### Baskin Engineering Policies

Please refer to Baskin Engineering's Admission to School of Engineering Majors section of the catalog for additional policies that apply to all Baskin Engineering programs. These policies include admission to the major and the need for students to obtain preapproval before taking courses elsewhere.

### Planners

The tables below are for informational purposes and do not reflect all university, general education, and credit requirements. See Undergraduate Graduation Requirements for more information.

The following are four sample academic plans that students can use to plan their sequence of courses in the major. The first two plans are suggested guidelines for students who begin their studies in their frosh year. Such students, if they plan carefully, will have several openings free to take other breadth courses they find interesting, or pursue an additional minor or major. The other two plans are for students transferring to UC Santa Cruz as juniors.

**Plan One: **This planner is for a student entering UCSC in their frosh year who is prepared to go directly into MATH 19A or MATH 20A.

Upper-div elective | |||

4th Year |
AM 129 | AM 147 | AM 170B |

Upper-div elective | AM 170A |

The SI general education requirement is satisfied by passing the capstone course AM 170B. The MF general education requirement is satisfied by passing any of the lower-division mathematical foundations requirements.

**Plan Three:**This is a sample planner for a transfer student. It assumes the student has taken the majority of their general education requirements prior to joining UCSC.

Upper-div elective | Upper-div elective |

**Plan Four: **This is a sample planner for a transfer student interested in the 4+1 program (e.g. thesis track; replace Independent Study with M.S. elective for coursework track). Note that students **must **take the graduate version of PDEs and Dynamical Systems courses (212A and 214 respectively) to count toward the M.S. core requirements. One additional elective must be taken during the M.S. year to ensure that there are at least 35 credits taken as a graduate student.
