This document contains questions about differential equations relating to a poisoned duck that ate a poisonous mushroom. It provides context about the rate at which the poison is spreading through the duck and asks the reader to: 1) Sketch a slope field for the rate of change of poison dp/dt at indicated points. 2) Use Euler's Method to approximate the solution to dp/dt with an initial condition over 5 steps. 3) Find a particular solution to dp/dt given another initial condition.
