The TAN function is a Math and Trigonometry function, and its purpose is to return a tangent of a number or angle. In this post, we show you how to use the TAN function in Microsoft Excel.

The tangent can be determined with a collection of mathematical formulas but is most commonly determined by dividing the sine function by the cosine function.

We want the slope, but all we have is the angle. What we need is a relationship that relates the two. This relationship is known as the “ tangent function,” written as tan (x). The tangent of ...

Sin, cos and tan are commonly used abbreviations for the three trigonometric functions sine, cosine and tangent.

In the paper, the authors find series expansions and identities for positive integer powers of inverse (hyperbolic) sine and tangent, for composite of incomplete gamma function with inverse hyperbolic ...
