Best ResponseYou've already chosen the best response.0i spose its possible, just use those"equations" as the F(x) stuff in the end

Best ResponseYou've already chosen the best response.0you might want to go about "reducing" the integrand to an addition of sin and cos....maybe

Best ResponseYou've already chosen the best response.0cos cos^2 cos(1sin^2) cos(x)(1  (1cos(2x)/2)) ... along those lines eh?

Best ResponseYou've already chosen the best response.0integral of sin^2 is known as x/2 + sincos/2 so you could use that

Best ResponseYou've already chosen the best response.0Well I have notes and an example problem, but it doesnt really make sense. He has the differential of the integral e^x^2 from a to b. He then takes partials. Fa = e^a^2 and Fb = e^b^2. Then apparently the differential is e^a^2 * da + e^b^2 * db. No sense.

Best ResponseYou've already chosen the best response.0Don't worry about it, I just wondered if anyone could make sense out of it, but obviously my teacher is drunk. He wrote his own "textbook" in Mathematica and he didn't do a very good job.

Best ResponseYou've already chosen the best response.0are you still talking about integral of cos^3? anyway yeah there are no elementary functions to describe integral of e^(x^2).
