Up to ten functions can be plotted in one coordinate system at one time. You may also use combinations or derivations of already defined functions.
If f1(x)=sin(x) and f2(x)=3*sqr(x), then f3(x)=2*y1^2-y2 substitudes f3(x)=2*sin(x)^2-3*sqr(x) f4(x)=f2(y1) substitudes f4(x)=3*sqr(sin(x)) f5(x)=y2' substitudes f5(x)=3/(2*sqr(x))
By double clicking with the left mouse button you may switch between panning and zooming, detectable at the mouse cursor. A right mouse click opens a popup menu which allows to set further options.
I chose this example because there were a surprising number of inquiries as to why the lower half of the horizontal parabola is not displayed for the root function.
The example shows that the lower half belongs to a different function.
The curves can be switched on and off individually with the switches on the right.
