Integrate 3 sin x
I know sin x would be - cos x
maybe this is not so hard....
chain rule - cos (x); x would just = 1 but it turned into a three.

So is the answer - cos (3x)?

i think -3cosx

why don't I have to integrate the 3 somehow? it remains unchanged? why wouldn't it at least get an x???

+C where C is a constant

myininaya · Answer

its a constant just bring it down and integrate sinx

myininaya · Answer

how would you take derivative of -3cosx
wouldn't you just bring the constant down and take derivative of cosx

anonymous · Answer

because it's a constant. similar to differentiation

anonymous · Answer

that dang +c  I actually write it out at the end of the problem and circle it before I even start. 

So the smart monkey would kick the 3 outside the integration symbol before even starting?
