?For the following exercises, find the slope of a tangent line to a polar curve
Chapter 1, Problem 241(choose chapter or problem)
For the following exercises, find the slope of a tangent line to a polar curve \(r=f(\theta)\). Let \(x=r \cos \theta=f(\theta) \cos \theta\) and \(y=r \sin \theta=f(\theta) \sin \theta\), so the polar equation \(r=f(\theta)\) is now written in parametric form.
\(r=4 \cos (2 \theta)\); tips of the leaves
Text Transcription:
r=f(theta)
x=r cos theta=f(theta) cos theta
y=r sin theta=f(theta) sin theta
r=4 cos (2 theta)
