In part a, I am having trouble seeing how you went from y=2 ln(t) to the y'= 2/t can you just explain that one step.
Also do you need to do both parts a/b, or is that just a way to check the answer? Thanks for the help!!
Hi KarlosK, so taking the derivative of a natural logarithmic function is simply . In your case your would be simply . By chain rule, after taking the derivative of the first function, theres is a function within a function which is the , so there for it becomes . Yet, yielding the final solution as .
