## What do you learn in Numerical Analysis I

Numerical Analysis I covers methods for solving mathematical problems using computers. You'll learn about error analysis, root-finding algorithms, interpolation, numerical integration, and solving linear systems. The course focuses on developing efficient algorithms to approximate solutions for complex mathematical problems that can't be solved analytically.

## Is Numerical Analysis I hard?

Numerical Analysis I can be challenging, especially if you're not comfortable with programming. The math concepts aren't too bad if you've taken calculus and linear algebra, but applying them to create algorithms can be tricky. The workload can be heavy with lots of coding assignments and proofs. But if you enjoy problem-solving and have a knack for programming, you might find it pretty manageable.
