The function f(x) to 1/f(x) or a to 1/a.
A trigonometric function of an acute angle in a right triangle that is equal to the ratio of the oppostie side to the longest side and is used to find lengths of similar right triangles. 
The measure of a central angle whose intercepted arc has a length of the circle's with a radius of 1, and is close to 57 degrees.  It  can be used as a ratio to find lengths of arcs in larger or smaller circles since all circles are similar.  
The process used to reverse or "undo" another operation.
A circle with a radius of 1 that is used for similar triangle ratios, radian angles and measures, solving many trig problems, graphs of wave patterns, and much more.
