In this lab, you are given a two dimensional unnormalized density function represented by target_density below. The goal of Question 1 of this lab is to build up a sampler that can output samples from the distribution proportional to . In Question 1 we will compute samples via Rejection Sampling. In part 1a we will build a sampler for a 1-dimensional projection of the density. In part 1b we will extend the approach to two dimensions. Throughout Question 1, we will assume that our computers have access only to normal and uniform random variables
