little bug: no multiplication sign when numbers are negative
When using p in a formula like f(x)=3x^2+px the "value" of p is correctly shown in a textbox, for negative and positive values of p.
But when I use the option Integral, the integral of f is shown as x^3+(0.5)(-3)x^2 when p=-3,
and x^3+(0.5)*3 x^2 when p=3
There is no multiplicationsign when p = -3, but there is one when p is positive
It would be nice if that could be fixed.
An example: ( look at the integral just above the brown text)
