Hi MHF,
There are two questions that are confusing me. I understand the material, but when I was working them out, I would get stuck (with algebra parts) and I do not know how to continue.
a) Find y'' by implicit differentiation.
I found y'=
(that's supposed to be a fraction)
What is y''?
b) If f = cot , find f'''( )
f'(x) =
What is f"? f"'?
Thank you very much!
