Section 4.3 Polar Coordinates. Use polar coordinates to solve the following problems, Express the polar equation \(r=\cos 2\theta\) in rectangular coordinates. Sketch polar graphs of: \(r=1+\sin ...

With the polar form of complex numbers established, the matter of Euler’s Identity is merely a special case of a+bi for a = -1 and b = 0. Consequently for the polar form re iφ , this makes r ...
