In this lesson, we will learn how to find the slope of a polar curve at a point and sketch this curve along with its tangent at that point.
Q1:

Q2:
Given a polar curve defined by π = π ( π ) , form an expression for the slope of the curve d d π¦ π₯ in terms of π and π .
Q3:
Find the slope of the tangent line to π = π at π = π 2 .
