If A and B are two angles in standard position in Quadrant I, find cos(A + B) for the given function values.
sin A = 8/17 and cos B = 12/13

Provide an example of a trigonometric function and describe how it is transformed from the standard trigonometric function f(x) = sin x, f(x) = cos x, or f(x) tan x using key features.

Whats the name of the vertical axis

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"
