Answer 8

heres what im doing....\[indefinite \int\limits x ^{45}\cos(x^{45}) dx \] becomes \[-1/45 \int\limits \cos (u) du\]
i need to convert these in to the limit of \[\int\limits_{{0}}^{\sqrt[45]{\pi}}\] and if x = \[\sqrt[45]{\pi} then (u) = what?\]

Answer 9

ok thanks..but how do it do the above?^^
