there is only one question so kinldy have a look and solve all parts of q5 in one hour only plz don't take too much time and take a thumb up plz
5. Consider the functions
e +e
a(x) =
and B(1) =

In this question, you may freely use the fact that 8(z) – a (r) = 1.
Verify that a'(z) = B(x) and B'(x) = a(r).
The function a is invertible. Use the Inverse Function Theorem to compute the derivative
(i)
(ii)
of a1. Simplify as much as possible, using the fact that B2(x)- a (x) = 1 to write your answer
without any a's or B's.
(iii)
the derivative of a" (this time without using the Inverse Function Theorem) and confirm that you
get the same answer as part (ii).
