Math 3BH – Castroconde Name: In-class Worksheet (11.1-11.2) I.D.#: 1. Sketch the parametric curve C: π 2 0 , cos , cos 2 - = = t t t y t x by plotting points. Indicate with an arrow the direction in which C is traced as t increases. 2. Eliminate the parameter to find a Cartesian equation for the parametric curve C: t t e y e x - = = , . 3. Find an equation for the line tangent to the parametric curve t t y t x - = + = 3 3 1 2 , 1 2 at the point corresponding to t = 3 . 4. Find 2 2 dx y d if 3 2 2 ,
