CAS bug?  mapet  11222002 Tan(x)integral from 0 to oo crashes my HP 40G. How about Hp 49G ?
Re: CAS bug?  Tom Sherman  11222002 I am crashing too!! What can the integral of sin, cos, or tan be, when integrated to infinity? Maybe Lewis Carroll could tell me.
Re: CAS bug?  axel  11222002 Integral of Tan(x) is ln(cos(x)) which has a singularity at x=pi/2 (and 3/2 pi, 5/2 pi etc). So the integral from 0 to x=pi/2 would be oo.

Re: CAS bug?  Vieira, Luiz C. (Brazil)  11222002 Hi; would this singularity raise to oo if PI/2 is not exact? Is the exactmode flag set? What about trying in Approximate mode? I did not try it, but I thought I could suggest it.
