Calc
Calc is a little byproduct of Plot. It is mainly the builtin calculator of Plot as standalone application.
Calc is easy to use, just enter your calculation in the lower text field and hit return to get the result in the upper textfield. The result of every calculation is stored in a variable (r0 ... r<n>). These variables can be used in later calculation. The Arrow-Up and Arrow-Down keys allows you to browse through calculation history.

Calc functions
Calc allow entering of mathematical expressions and supports the following functions:
| +, -, *, /, ^, ** | arithmetic operations |
| %, mod | modulo |
| ( ) | grouping |
| rad(x), deg(x) | radian, degree conversion |
| sin(x),cos(x),tan(x) | trigonometric functions |
| asin(x),acos(x),atan(x) | inverse trigonometric functions |
| sinh(x),cosh(x),tanh(x) | hyperbolic functions |
| asinh(x),acosh(x),atanh(x) | inverse hyperbolic functions |
| ln(x),log(x),log2(x_ | natural and logarithm to basis 10 and basis 2 |
| exp(x), exp2(x) | exponent for basis e and 2 |
| sqrt(x) | square root |
| cbrt(x) | cubic root |
| pi | 3.14159265359 |
| e | 2.71828182846 |
| <name>=<expression> | defines a user variable |
There are some special commands in the calculator:
| clr | reset the calculator and deletes all variables and the history but not the user variables. |
| clrall | reset the calculator and deletes all variables and the history. |
| vars | show a list of available variables |
| hist | show the calculator history |
| quit, ""exit"" | terminate the program |
| help | show help |
