# Quiz 5

Remarks:

• (Section F) Notice that when taking the derivative of $e^{-x^2}$, please use the chain rule appropriately. Always ask yourself what are the inner function and the outer function.
• (Section G) It is a bit hard to take the derivative of $\sin(e^{-x})$ since it is actually the composites of three functions. You can use the chain rule twice to derive the answer.
