STATEMENT-1 : If `f(x)=int(dx)/(sin^(1//2)xcos^(7//2)x)`, then the value of `f((pi)/(4))-f(0)` is equal to `(12)/(5)`.
and
STATEMENT-2 : To find the `intsin^(m)xcos^(n)xdx` if `m+n=-ve` even, then we can substitute `tanx=t`.

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explantation for Statement-1

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explantation for Statement-1

C

Statement-1 is True, Statement-2 is False

D

Statement-1 is False, Statement-2 is True
