In particular, they can determine polar coordinates of a point given in rectangular coordinates, and vice versa. Students represent equations given in rectangular coordinates in terms of polar coordinates. Students are familiar with complex numbers. They can represent a complex number in polar form, and know how to multiply complex numbers in their polar form. Students know De Moivre's Theorem, and can give n-th roots of a complex number given in polar form.
Students are adept at using trigonometry in a variety of applications and word problems.
