chain rule
Q: let . Show that...
a) , where
b)
I got the first part just fine, but I am stuck on part b. I'm not sure what really is. If I let the derivative equal 1, then everything falls into place and I get equivalent answers, but I doubt thats how I am supposed to do it. Do I solve for and then evaluate that as my function for ?
Any suggestions?
Thanks,
Oh, and how do I make my parenthesis proportional to what’s inside them?! Its angering me....
