I got a question regarding the derivatives of a log but in a fraction. Here is an example:
3x^2 / ln(x)
This isnt a homework problem but im studying for a quiz tomorrow and want to be ready for anything. Would I use the quotient rule for this problem?
Also another quick question. Its kind of stupid so sorry.
But in this question how do i get from step 1 to step 2.
y = sin (7 ln(x))
(derivative) dx/dy y= cos(7ln(x)) (7/x)
Step 1: y(1) = cos (7ln(1)) (7/1)
Step 2: y(1) = cos (0) (7)
Im guessing ln (1) = 0 ?
thanks for your help
