Obamanation.

4. jtvatsim

that's $\cos(\frac{3\pi}{2} + h)$ right?

5. ksaimouli

yes

6. ksaimouli

$-\sin(\frac{ 3\pi }{ 2 }+h) \frac{ 3 \pi }{ }$

7. ksaimouli

3 pi/2

8. jtvatsim

close, I don't think you should have a 3pi/2 though... since the derivative of 3pi/2 is 0.

9. ksaimouli

hmm whats the answer

10. jtvatsim

So assuming we are taking the derivative with respect to h, the deriviative of the inside by the chain rule is 1. So we just multiply -sin(3pi/2 + h) by 1 and get -sin(3pi/2 + h).
