Qn 4 involves using product rule and chain rule. After differentiating, look for common factors to factorise so that it will not be very tedious to do the expansion.
Qn 5 uses quotient rule. When curve cuts x-axis, value of y will be 0. Thus, manipulating the original equation will get you the value of x which you can use to substitute into the dy/dx equation.
