Functions are one of the most fundamental concepts in mathematics, forming the foundation for topics in algebra, calculus and many other areas. A solid understanding of the basics of functions, ...

The tangent function is a trigonometric function that is derived from the sine and cosine functions. In right-angled triangles, the tan of an angle (θ) is the ratio of the side opposite the angle to ...

Mathematics is a fascinating world, especially when it comes to finding the inverse of a function. An inverse function is a function that undoes the action of another function – meaning, if you input ...

We show that the rational functions associated with the lemniscate functions and primary numbers of Gaussian integers, defined by Eisenstein, has a symmetrical relation with respect to the zeros and ...
