Answer:
Required solution (a) (b) 40.
Step-by-step explanation:
Given,
(a) Let,
Then,
Integrating we get,
Differentiate this with respect to y we get,
compairinfg with of the given function we get,
Then,
Again differentiate with respect to z we get,
on compairing we get,
(By integrating h'(z)) where C is integration constant. Hence,
(b) Next, to find the itegration,
