Draw2d

Function: draw2d (<option>, <graphic_object>, ...) This function is a short cut for draw(gr2d(<options>, ..., <graphic_object>, ...)).

load("draw");
draw2d(nticks=1000,key="cos x", explicit(cos(x),x,-1,-0.98),color=red,key="Taylori polünoom",explicit(1-x**2/2+x**4/24,x,-1,-0.98),terminal=pdf,file_name="h:\\ma3\\17s\\graafik2");

It can be used to plot a unique scene in 2d.

To make use of this function, write first load(draw).

See also draw and gr2d.
