In this video, we'll multiply two complex numbers together, and then convert the product to polar coordinates.

Complex numbers (numbers containing real parts and imaginary parts, i) can be written in terms of polar coordinates r and theta.

This video explains how to find the surface area of the three-dimensional figure that's created when you rotate a polar curve around a linear axis.

You'll need to find the derivative of r with respect to theta and then plug it into the formula in this video to find arc length of a polar curve.

You'll need to find the derivative of r with respect to theta and then plug it into the formula in this video to find arc length of a polar curve.

To find the area between two polar curves, first find the points of intersection that define the interval, then use the formula for area between polar curves.

This video is an example of how to find the area inside one loop of a polar curve.

To find the area inside a polar curve, find the limits of integration and then use the polar area formula from this video.

The easiest way to sketch the graph of a polar curve is to first sketch it on a cartesian coordinate system, and then translate the cartesian graph onto a polar coordinate system.

To convert a polar equation (an equation in terms of polar coordinates (r,theta)), just use the conversion formulas in this video to replace all of the r and theta variables with x and y variables.
