7.0 Students know the tangent of the angle that a line makes with the x-axis is equal to the slope of the line. 8.0 Students know the definitions of the inverse trigonometric functions and can graph the functions. 9.0 Students compute, by hand, the values of the trigonometric functions and have the inverse trigonometric functions at various standard points. 12.0 Students use trigonometry to determine unknown sides or angles in right triangles. 13.0 Students know the law of sines and the law of cosines and apply those laws to solve problems.
Students determine the area of a triangle, given one angle and the two adjacent sides.
15.0 Students are familiar with polar coordinates. In particular, they can determine polar coordinates of a point given in rectangular coordinates and vice versa. 16.0 Students represent equations given in rectangular coordinates in terms of polar coordinates. 17.0 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.
