Special Trigonometric Functions
It is always important to remember the basic properties of elementary trigonometric graphs. Many graphs on the AP test will be variations of the graphs below. The table below shows the periods and amplitudes of these functions.

y=a sin bx or y=a cos bx2pi/|b||a|
y=a tan bx or y=a cot bx2pi/|b|NA
y=a sec bx or y=a csc bx2pi/|b|NA
