Where Do Polar Curves r=5sin(theta) and r=5cos(theta) Intersect?

[joshuapeterson]

Determine the polar coordinates of the two points at which the polar curves r=5sin(theta) and r=5cos(theta) intersect. Restrict your answers to r >= 0 and 0 <= theta < 2pi.

Aren't you going to at least attempt it yourself? r= 5 sin(theta)= 5 cos(theta). What do you get if you divide both sides by 5 cos(theta)?
