Solution
Let’s go through each question one by one. I’ll break down each question and provide detailed solutions.
Question One
(a) Find if and .
To find , we can use the chain rule since .
- Differentiate with respect to :
- Substitute :
Answer: .
(b) If , show that and .
-

This integral requires integration by parts and is a bit more complex. If needed, I can provide a step-by-step solution here.
Question Two
(a) Find the coordinate of the point of where the gradient = 0.
To find where the gradient is zero, set .
- Differentiate :
- Set : Solve this quadratic equation for .
