This equation is "a quadratic in sine"; that is, the form of the equation is the quadratic-equation format:. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. The same sort of thing works here. If you square something, you can't just square-root to get back to what you'd started with, because the squaring may have changed a sign somewhere. Can any square of a tangent, or of any other trig function be negative?
In Geometry, students learned about the trigonometric ratios sine, cosine, and tangent. In this unit, we Amplitude & period of sinusoidal functions from equation.
