Homework Statement
Can you please explain and show the steps of the ff.?
1. Find the derivative of the ff. f(x) = cos^5(2x^6)
2. Suppose f(1) = 2, f '(1) = 3 and f '(2) =4, then f^-1(2)=?
3. Find all points on the curve 2x^3 + 2y^3 -9xy= 0 where you will have a horizontal and vertical tangent lines.
Homework Equations
chain rule, i guess, and then the dx/dy thing if you have a y variable
The Attempt at a Solution
1. f'(x)= -sin(2x^6)* 2 ( but its not one of the choices)
2. I don't know what equation to use!
3. horixontal means slope is 0 and vertical means slope is undefine. I don't know what equation i need to set equal to zero and to undefine
