What differences is there between a sinx and cosx function?
Do they both use this equation?
y=Asin(BX+C)+D

That's too in depth for me.
I just wanted to know the difference between
y=sinx and y=cosx when graphed.
 
Ok, try this: http://faculty.ed.umuc.edu/~swalsh/Math%20Articles/Graphing%20Sin%20Cos.html

Maybe cristo just missed it, but Ry122 is actually right, cosine can also be expressed in that form of asin(bx+c) + d.

This happens because sin (90degrees-x)= cos x.

So in answer to your original question, the difference when graphed between sin x and cos x is that the cos graph is the same as sins, moved back 90 degrees to the left.
