Chapter 11.3, Problem 6QR

Find the equation of the curve whose parametric equations are x = 1 + 4 cos 0, y = 2 + 3 sin 0, 0 € R.

Consider the parametric curve defined by x = 2020 cos t y = 2020 sin t TC Find the slope of this curve when t = 3 -1010V3 -V3 v3 V3 O 1010

Eliminate the parameter in the parametric equations x =7+ sint, y = 2 + sint, for 0sts and describe the curve, indicating its positive orientation. How does this curve differ from the curve x = 7+ sin t, y = 2 + sin t, for 7stsn?
