int() asks for assumtions if required

cleanup MaximaControl done

This resets the assume list.

takeover MaximaControl int(), diff(), sum() and lim() now use Maxima

Maxima cannot compute the integral without knowledge about the sign of x.0

x ε ε.0 x x.0 / (* :

x y y.0 x x.0 / (2^* :

x ε 1 x y x diff (2^+ sqrt * x 0 x.0 int #

x.0 0 > assume Maxima x.0 0 >

x ε 1 x y x diff (2^+ sqrt * x 0 x.0 int ε.0 4 y.0 2^* x.0 2^+ (32 /^x.0 3^- (* 12 y.0 2^* /

int() now treats units always as positive

Therefore, explicit sign assumptions are not required. This is a convenience feature. The units need not be defined.

This also works for ODE solving
