CAS loops forever on emulator and freezes the physical device.

Just taking the indefinite integral of \(\int \tan \left ( \sin \left ( x \right ) \right ) dx\) produces a result that is 122,286 characters long!

integrate((-5*sin(x)+6*e^(cos(x)*((cos(x))²-(sin(x))²-1)/((cos(x))²+(sin(x))²)+sin(x)*2*cos(x)*sin(x)/((cos(x))²+(sin(x))²))*sin(

+(sin(x))²)))²-216*(cos(x))²*(sin(x))²+132*cos(x)^4+132*sin(x)^4+24*(cos(x))²-24*(sin(x))²+2),x)

Impressive if the result is correct.
