Students know the Laws of Sines and the Law of Cosines, and apply them to problems. Students determine the area of a triangle given one angle and the two adjacent sides. Students are familiar with polar coordinates. 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.
