Function plotter
Supported constants
The constants Pi (=3,1415...) and e (=2,7183...) will be recognized.
Supported operators
The usual basic arithmetics +, -, * and / as well as the modulo operator % will be recognized. Point before dashes is taken into account and brackets are recognized.

| cos(x) | Cosine of x (x is assumed to be radian) |
| tan(x) | Tangens of x (x is assumed to be radian) |
| asin(x) | Arcus sine of x (x is assumed to be radian) |
| acos(x) | Arcus cosine of x (x is assumed to be radian) |
