Simple Calculations
    To evaluate an arithmetic expression, you should enter expression using keyboard
and/or
Calculus Panel and press Enter. ArtSGraph will display the result of calculation
in the next line.
Math expressions have usual syntax. Expression is constructed using numbers, variables,
brackets and signs of
arithmetical operations. Spaces are not allowed. Space is used to
separate two expressions in a line.
Examples:
                  1+3/4+sqrt(4)
                  (1+3.12)^2/(1*6.2-14)+5
Expression can include variables. For example, you can assign an expression with variables
to another variable:
                 f=sin(2*x)+ln(3*y)
Than you can assign values to variables x and y and evaluate the expression by typing
                x=3 y=5 f
                x=-2 y=1 f
etc.
The following example calculates value of derivative of sin2(x)+4 at x=4. To obtain correct result
variable x must not be defined prior to execution of the command.
                 f1=diff(sin(x)^2+4,x)  x=5 f1
