# MATH 209: Computing in Mathematics

Prerequisites & Bulletin Description

## Course Description

Introduces basic sequential programming constructs in scientific computing using the Python Language. Uses programming projects to review and reinforce material from Calculus and Linear Algebra. Introduces essential modeling and programming concepts.

## Student Learning Outcomes

 SLO #1 Develop and write efficient Python programs. Read and understand programs written by others. SLO #2 Numerically compute the derivatives and integrals of functions using their own Python programs. SLO #3 Numerically solve first order differential equations, find the roots of functions and find solutions of large linear systems. SLO #4 Understand, develop and write graph search and list sorting algorithms. SLO #5 Solve probability problems using computer simulations. Perform linear regression with cross-validation on a data set to develop an efficient linear model.

## Evaluation of Students

Based on homework assignments, quizzes, midterm and final exam, and projects.
