Need help with number 5,6,& 7 please!! Thank you!
5a) Use the chain rule.
5b) Use the chain rule. For logarithmic differentiation, you the formula
5c) , so
6) Rewrite for y. For example, Use the tangent line formula. Given the coordinate (a, f(a)), the equation of the tangent line is y-f(a)=f'(a)(x-a)
7) Find the derivative, and set y'=0 and solve that equation. The solutions you get for y'=0, sub that into y, and you'll find out the local extremas.
This is not calculus 3. This is calculus 1, just very difficult calculus 1 problems.
