**Inverse Trigonometric Functions**

In a problem where two trig functions are not inverses of each other (also known as "inverse trigonometric functions"),

(1) replace the inverse function with a variable (which represents an angle),

(2) use the definition of the inverse function to draw the angle in the unit circle and identify one coordinate,

(3) find the missing coordinate (use Pythagorean Theorem, for example),

(4) use the coordinates to find the missing value.
