Finally added the sliders to the SecuCalc app, now you can get a feeling for functions much more easily :).

The examples are:
- sin(S1(0,5)*x)/(S2(0,5)+x^2), as examples for sin times 1/(something+x²)
- S0(-3,3)*x^2 + S1(-3,3)*x + S2(-3,3), allowing to experiment with a*x²+b*x+c
- vec(sin(x*y*S0(0,5)), y, -9, 9, .3), just for fun, showing that it works for 2D, too
