Question

integration of (sin^5x)*(cos^3x)dx

Answer 1

split cos^3 x = cos x * cos^2 x
write cos^2 x = 1- sin^2 x
then its easy to see that u = sin x
du =cos x dx.

Answer 2

so do you leave sin^5x as it is

Answer 3

yes,
then you'll use it...
s^5 (1-s^2) c dx [s=sin, c=cos]

Answer 4

s^5 (1-s^2) c dx = (s^5 -s^7) cdx

Answer 5

ah i see how that tricked me i tried to think it was a half angle formula or something

Answer 6

so, now can you solve that integral ?

Answer 7

yea i can thanks a lot bro

Answer 8

welcome ^_^

Answer 9

math not my best subject :P

Answer 10

it became my best subject, after lot of practicing :)

Answer 11

1 question though can you split sin of x to solve also

Answer 12

yes,but that will be more complicated....but yes.

Answer 13

ah i see ty again

Answer 14

if i need help again asking you :P
