Answer:
Step-by-step explanation:
1. Given the integral function , using trigonometric substitution, the substitution that will be most helpful in this case is substituting x as
i.e
.
All integrals in the form are always evaluated using the substitute given where 'a' is any constant.
From the given integral, where a = 7 in this case.
The substitute will therefore be
2.) Given
cross multiplying
3.) Rewriting the given integral using the substiution will result into;
