We see that and to find , apply the chain rule.
Note that the chain rule is .
So we see that
Now substitute into the equation for the product rule:
If , then
Can you take it from here?
I don't see anything wrong with your answer. Make sure you copied down the problem correctly...otherwise, I'd have to say the book's answer is wrong.2. secx^2
I always get the wrong answer everytime and can't figure it out..
h'(x)= secxtanx X 2(secx)
The answer shows up as 2xsecx^2tanx^2
help!! I need help understanding the chain rule and I got no idea how to do problems like these!!
