Name ________________________ Math 172 Spring 2019 Written Assignment 9: Parametric Equations and Polar Coordinates Be sure to show all of your work. You may discuss these questions with other students or your TA, but electronic help is not permitted! 1. Give parametric equations that describe a full circle of radius 𝑅 , centered at the origin with clockwise orientation, where the parameter varies over the interval [0,10] . 2. Consider the parametric equations ? = 𝑡 2 + 2 and ? = 4𝑡 for −4 ≤ 𝑡 ≤ 4 . (a) Make a brief table of values of 𝑡 , ? and ? .
Name ________________________ 2, continued. (b) Plot the (?, ?) pairs in the table in part (a). Use those points to plot the complete
