Prime: Another Warm Start


Here is another warm start (or is it a cold start? - - it sure feels like a cold shower) that could actually happen to anyone who uses the calculator as an exploring tool, like exploring indefinite integrals of transcendental functions.

Set checkbox "complex" in CAS settings, to allow for complex results in CAS variables.

In CAS view, try int(sin(x)*ln(x),x), or int(cos(x)*ln(x),x), or also int(sin(x)*ln(abs(x)),x), etc.

However, if checkbox "complex" is not set, all is well, and a subsequent Eval returns the desired results.
