Discussion:
I) Find the slope of the tangent line to the given polar curve at the point specified by the value theta.
a) 5 = sin(theta), theta = pi/6
b) r = 1/theta, theta = pi
c) r = 1 + cos(theta), theta = pi/6
II) Find the points on the given curve where the tan line is horizontal or vertical.
a) r=3cos(theta)
b) r=1+cos(theta)
c r=e^0
d) r=cos2(theta)
