Calculus 2: Polar Coordinates (14 of 38) How to Find the Slope of a Function Ex 1

In this video I will find the slope of an equation expressed in polar coordinates, where r=1+2sin(theta). Knowing the relationship between Cartesian and polar coordinates, x=rcos(theta) and y=rsin(theta), from previous video we found (dy/dx)(r=0)=tan(theta). But now we need to find theta=? when r=0, then substitute into (dy/dx)(r=0)=tan(theta).

The fact that he does angle calculations in degrees rather than radians is mind-boggling. Really great video!
