I agree.
Actually I wanted to test numerical integral in some calculators that hasn't symbolic integration, but if I need to know the value of an integral for working purpose I search for it in a CAS machine (49, 50g, Prime...) if possible... Said that, if one doesn't remember by hearth the antiderivative (to do it by hand) and has got in that moment only a calculator like HP15 or HP41 or HP42s and so on, better trying numerical integration than nothing...
Anyway, this particular integral was for me a way to test the behaviour and potentiality of some beloved calculators of ours.
