Chapter 11.2, Problem 10QR

B) Find the length of the curve r = 1+ sin(26) V20

Graph the curve x = cos t + 2 cos 2t y = sin t + 2 sin 2t to discover where it crosses itself. Then find equations of both tangents at that point.

Find the slope of the curve whose parametric equation is given by y = t³ + t²+ 1/t and x = t⁴ + 3t² when t = 1/2.
