Please dont type the answer out for some reason when the answer is typed out I can't see the full solu

5. For the constant numbers a and b, use the substitution x = a cos² u + b sin² u, for 0 <u<, to
show that
dx
| = =
= 2arctan
√(x − a)(b − x)
x-a
√b - x
+ C₂
(a < x < b)
Hint. At some point, you may need to use the trigonometric identities to express sin² u and cos² u
in terms of tan² ա.
