Howto use program: just enter the expression, the variables and their values, and finally, press ''=''.
In expression you can use the usual operators, such as ''+'', ''-'', ''*'', ''/'', and ''^'' - involution, ''%'' - modulo, ''!'' - factorial.
Also part of expression may be in parentheses to change priority operations.
In expression you may use constants:
$pi - number Pi (3.14159...)
$e - number e (2.71828...)
It is possible to save the function and used variables for subsequent calculations.
When you enter numbers, you can use the E notation, for example, 1.3e5 i.e. 130000.
Value of the trigonometric functions depends on the position of the switch:
DEG - degrees
RAD - radians
GRAD - gradians
