Best ResponseYou've already chosen the best response.0okey so \[\frac{ du }{ dx }=\sin x\] \[\sin dx =du\] \[\int\limits_{0}^{py/3} u^{3} *1 du\] then you get

Best ResponseYou've already chosen the best response.1I would just sub that u back after we take the antiderivative so I won't have to change limits :P

Best ResponseYou've already chosen the best response.1it's only half done @Xlegalize next you have to evaluate the integral

Best ResponseYou've already chosen the best response.1wahhhhhhhh I don't wanna sub old limits and get new ones ......... I rather just sub u back after antiderivative step and just evaluate so easier lezl

Best ResponseYou've already chosen the best response.1it was half done.. evaluating was missing at x = 0 cos(0) is 1

Best ResponseYou've already chosen the best response.0thats exactly what I did after I got the answer 0.265, the correct is 0.234

Astrophysics

Best ResponseYou've already chosen the best response.1or is that suppose to be pi/3?

Best ResponseYou've already chosen the best response.0soo strange.. now I get the right answer. maybe it depends on how I plug it into the calc? tho it shouldnt. But I did like this. cos(pi/3)^4/4+cos(0)^4/4

Astrophysics

Best ResponseYou've already chosen the best response.1is that suppose to be pi/3 or pi/3
