differentiate implicitly.

4. swin2013 Group Title

yea... i think i did it wrong. i know when there's a y present you multiply by dy/dx

5. baldymcgee6 Group Title

Well, you see, we're taking the derivative with respect to x, so when we come upon a y, we just write "the derivative of y" which is dy//dx or y'

6. baldymcgee6 Group Title

So what is the derivative of sin(xy)

7. swin2013 Group Title

cos(xy)

8. baldymcgee6 Group Title

But beacause of the chaine rule we have to multiply by the derivative of the inside.

oookk i was stuck on that part, i wasn't sure if i multiplied dy/dx correctly
