Transformations of Functions. This applet will help you in visualizing the effects of transformations on functions. ... If you wish to change the function, type a new one in here. f(x) = Type "^" for ...

Theta functions are also "super-symmetric," meaning that if a specific type of mathematical function called a Moebius transformation is applied to the functions, they turn into themselves.

Some authors rely upon Cremona transformations, ... Algebraic Geometry and Theta Functions. By Prof. Arthur B. Coble. (American Mathematical Society Colloquium Publications, Vol. 10.) ...
