Graphs

Numerics supports graphs with following syntax:

plot(f(x);....;g(x),from:to,step)

where

• f(x), g(x) are functions to plot
• from:to is range for x
• step is size of step of x moving from point from to to

Try, for example:

* plot(cos(x)) is the same as plot(cos(x),-100:100,0.5)

* plot(cos(x);sin(x))

* plot(x^2,-10,10)

* plot(sin(x);tan(x);10*sign(x),-10:10,0.1)
