`int_(0)^( pi)|sin x|dx`

int_(0)^(pi) sin 3x dx

Evaluate the following integral: int_0^(2pi)|sin x|dx

int_(0)^(pi) [2sin x]dx=

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

int_(0)^(pi/4) sin 2x dx

int_(0)^(2pi)[|sin x|+|cos x|]dx , where [.] denotes the greatest integer function, is equal to :

If the definite integral I=int_(0)^(pi)sin[x] dx=sum_(epsilon=0)^(n)a_(epsilon)sin epsilon . (where, [.] is the greatest integer function), then the vlaue of (a_(n)+n)/(pi) is equal to

int_(0)^(1) |sin 2pi x|dx id equal to

If A= int _(0)^(pi) (sin x)/(x ^(2))dx, then int _(0)^(pi//2) (cos 2 x )/(x) dx is equal to:

The value of the integral int_(0)^(pi//2) |sin x-cos x|dx , is
