Tangent

Tangent is a trigonometric function. Tangent can also be graphed. When trying to find an angle of a right right triangle, you would use tangent by saying tan(angle)=opposite/adjacent. The graph of tangent is not continuous. No matter what transformation the tangent graph goes through, there will always be infinite zeros. There are various trig identifies concerning tangent, including sum/difference, half angle, and double angle identities. Tangent is equal to sine over cosine.
