Question

INSTANT FAN/MEDAL:
Find the slope of the tangent line when theta=pi/4 for the polar graph r = 4 cos θ.

Answer 1

responses are 1,0,-1, and -sqrt(3)

Answer 2

Altho I don't remember it, there is a formula for the slope of the tangent line to a polar graph. Please refer to your textbook or the 'Net to find this formula.

Mind typing it out here?

Answer 3

I solved and got zero.

Answer 4

glad you've located the formula.

Is zero a possible slope value? If so, give an example. If not, explain why not.
