# DAY 1

# Lecture Notes

#### Day 1 Lecture Slides

All of the notes from the intro of day 1. This includes intro to computational astrophysics, overview of N-body motion and the specific application of 2-Body motion (both analytically and computationally).

# Code

#### Plot Analytical 2-Body Problem

Some python code for plotting an elliptical solution for the 2-Body problem.

#### Plot Analytical + Numerical 2-Body Problem

Some python code for plotting an elliptical solution for the 2-Body problem. This includes the analytical solution and some sudo-code for setting up numerical integration with a Euler's-type integration scheme.

# Resources
