Question

what is the increasing/decreasing intervals of f(x)=sin(x) [-2pie,2pie]

Answer 1

hey c:

Soooo, is this for calculus? or just basic trigonometry stuff? :O
I'm just curious which approach you're using for this problem.
Derivative?

Answer 2

@zepdrix, i think im on the parent functions. We are learning to identify the function based on a graph. and i must find the intervals of decreasing/increasing, domain/range, odd,even or neither of these function graphs.

Answer 3

im stuck with the sine/cosine function graphs

Answer 4

Here is a nice graphing utility that we can use:

If you have your own, that's ok too.
But this one is interactive, so it's kind of nice :)

Answer 5

y-intercept = heart? aw so cute c:

lol jk

Answer 6

lol xD, i was rushing to copy the notes that my teacher wrote.. no clue on what i wrote on the bottom..

Answer 7

We're restricted to this little window, I think that's what we want to call our domain..... that's what we would normally do at least.. 0_O
