Question

Evaluate the integral:
(integral sign) (5 sin xcos xdx)

Answer 1

If you can show me how to make the integral notation, I'd be more than willing to run your questions into Maple 14.

Answer 2

this is do-able :)

Answer 3

use change of variable...

u = sin(x) du=cos(x) dx dx = du/cos(x)

5 u cos(x) du
-----------
cos(x)

[S] 5u du

Answer 4

5u^2
---- + C
2

substitute the u = sin(x)

5sin(x)^2
-------- + C ; but check to see if I m right

Answer 5

Sorry, I know nothing. I'm just a freshman in high school.

What are you saying when you write "(integral sign) (5 sin xcos xdx)"

Answer 6

its calculus

Answer 7

it means you want an equation that will derive down to "5sin(x)cos(x)"

Answer 8
