Question

integration
why isn't e^cosx integrated into sinxe^cosx?

Answer 1

is derivative of
sin x e^cos x = e^ cos x ?

you know integration is also anti-derivative, right ?

Answer 2

anyways
you can integrate e^cos x by trying
u =cos x

Answer 3

yeah and sinx is differentiated into cosx right?

so cosx should be sinx

Answer 4

correct
integral of cos x is indeed sin x + c

Answer 5

so it should be 1/cosx instead?

Answer 6

because derivative of (sin x +c) is = cos x

Answer 7

i doubt integral of e^cos x exist

even if it does, it won't be in terms of standard function

Answer 8

what should be 1/cos x ?

Answer 9

sorry i mean -1/sinx • e^cosx

as the integrate of e^cox because that's what i get...

Answer 10

1/sinx ** not negative

Answer 11

ohs hoot they said to differentiate not integrate wow
i am so careless

but thanks for helping! ^^

Answer 12

lol, no problem:)
welcome ^_^
