I missed my last math lecture and now im reallllly confused. And this hw is due tonight. The question is:

Suppose u(t)=w(t^2+5) and w'(6)=8. Find u'(1).

Honestly this seems like an entirely different language to me :(

take the derivative of both functions ... note the use of the chain rule for the composite function w
