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) |
