The build-up of trigonometric functions:

If you know two intersection points, with the same y-value that that is 2/4 of the period

Periodic function:
f(x) = f(x+T)
A function that repeats itself
Ex.
(Trigonometric functions are all periodic)

Period:
1 up and 1 down

Graphing of Trigonometric functions:
Amplitude is pretty easy to graph as the first point is 1, so simply just multiply the amplitude by the y-intercept

Even and Odd properties of trigonometric functions:

Sin(x)Odd
Cos(x)Even
Tan(x)Odd
Csc(x)Odd
Sec(x)Even
Cot(x)Odd
—————————————-

Inverse Trigonometric Functions:
They give you the angle from the side ratios of Sin, Cos, Tan, Csc, Sec, and Cot.
