Evaluate `int _(0) ^(pi) || sin x |-| cos x || dx`

Evaluate: int_(0)^((pi)/(2))|sin x-cos x|dx

Evaluate int_(0)^(2pi) [ sin x + cos x] dx where [ ] denotes the G.I.F.

Evaluate int_(0)^(pi) sin^(7) x. cos^(5) x dx

Evaluate : int_(0)^(pi//2) sin^(3) x cos x dx

Evaluate int _(0)^(pi//2) sin^(4) x. cos^(6) x dx .

Evaluate int _(0)^(pi//2) sin^(4) x. cos^(6) x dx .

Evaluate int _(0)^(pi//2) sin^(4) x. cos^(6) x dx .

Prove that int_(0)^(a) f(x) dx = int_(0)^(a) f(a-x) dx . Hence, evaluate int_(0)^(pi//2) (sin x - cos x)/(1+ sin x cos x) dx.

Evaluate int_(0)^(pi//2) (1)/(sin x + cos x) dx

Evaluate :int_(0)^((pi)/(2))(sin x+cos x)dx
