the fuck is this
what rule do I use

[Mass]

uh

something with logarithms and trigonometric functions


no idea

[flibitijibibo]

Wait, I don't know what I'm thinking. Lemme write it out one more time.

∫ (e^sin(x)cos(x))dx

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

∫ (e^u) du

e^u

e^sin(x)

Aw, it didn't show later posts. Fuck.

You forgot about the second term that a product rule creates so that's wrong...

[Timo]

Integration by substitution, use u = sin x.
du = cosx dx, so all you need to integrate is e^u

[Con]

Integration by substitution, use u = sin x.
du = cosx dx, so all you need to integrate is e^u
I'd forgotten all about that. Seems so easy now, thanks!

du = cosx dx, so all you need to integrate is e^u du

ftfy, but yeah

Like I said on AIM:

math s(x))dx

at least math proves sex is fun.
