This week we learned about the chain rule..
this is supposed to be the hardest
concept to learn in calculus because
there is not a set of operations to follow
when doing it. so you kinda
just have to know when to spot it
this is the most that you have to follow.
first you have to find the inside and outside
after you follow this
d/dx=f(g(x))=f^1(g(x))xg^1(x)
here it is in english: derivative of outside, recopy inside,
then multiply by derivative of inside
here is an example:
d/dx(x^2+1)^3
the outside is y=(u)^3
the inside is u= x^2+1
3(x^2+1)2x
=6x(x^2+1)^2
that is your final answer.
good luck to everyone on the exam.
