import numpy as np
# NOTE: numpy uses radians for its angles

# constants
PI = np.pi
cos = lambda ang: np.cos(ang)
ncos = lambda ang: -1*np.cos(ang)
sin = lambda ang: np.sin(ang)
nsin = lambda ang: -1*np.sin(ang)

To set up openra on AWS EC2

Disclaimer: This is not the best architected solution, so no guarantees on up-time

PreReqs:

• Have an AWS account
• Know basics of ssh and bash

Setting up the EC2 Server:

1. Launch an EC2 with a Ubuntu OS. I used ami-059e7901352ebaef8 on a t2.micro
