Find the slope of the tangent line when for the polar graph r = 1.

Question

Find the slope of the tangent line when  for the polar graph r = 1. (5 points)

answer choices

	1
	-1
	0

Answer 1

pi/6 = 30 degrees

the point on the circle with radius 1 with angle 30 is (1,sqr3)

the tangent line is negative, downward sloping at that point on the circle

an angle of 45 degrees would have a tangent line with slope = -1

the only expected answer is -sqr3 = - 1.732
