- * Practice: Chain rule. (6 problems with a guiding text)
- $\rhd$ Identifying composite functions (8:12) Find $f(g(x))$ when $f(x) =1+x$ and $g(x) = \cos(x)$. Next, identify $g(x) = \cos(\sin(x)+1)$ as the composition of functions. What about $f(x) =\sin(x)\cos(x)$? Is it a composition of functions?
