Trigonometric Function
Definition:
The trigonometric functions are transendental functions based on the ratios of the the sides of a right triangle. They include sine, cosine, tangent, secant, cosect and cotangent. The graphs of trigonometric functions are periodic in nature due to their relationship to the unit circle.
Transformational Form of a Trig Function:
VS = Vertical Stretch, "the amplitude"
VT = Vertical Translation, "sinusoidal axis"
HS = Horizontal Stretch, HS = old period/new period
HT = Horizontal Translation, "start on x"
