I am having some trouble with a few problems I've been working on.
Find the derivatives of the function
Step was was recognizing the product rule for
so I have
but I am not sure that it is right
Problem number two: Find the derivative of
this one threw me a monkey wrench right away since the argument to arccos is only x and not a function of x. even if it were more then just x i'm still scratching my head on how to start this one
I figured to used the identity that
So I then went to complete the square to give me what I wanted
so then my denominator turned into 7 + (3x+1)^2 which I figured was wrong. A little confused on this one.
Same for this last problem
any help would be appreciated!!!
