Find the area inside both r = 2 sin(20), r = 2 cos 0

differentiate

Graph r = 1 / ( 3 cos ⁡ θ ) for − π / 2 < θ < π / 2 and r = 1 . Then write an iterated integral in polar coordinates representing the area inside the curve r = 1 and to the right of r = 1 / ( 3 cos ⁡ θ )

b. How would you rewrite each expression if it was an integrand for a trig. integral? Just the first step please. sin³xcosx sin²x csc³xcot³x
