int_(-(pi)/(2))^((pi)/(2))|sin x|dx

If for a real number y,[y] is the greatest integral function less,then or equal to y, then the value of the integral int_((pi)/(2))^((pi)/(2))[2sin x]dx is -pi (b) 0(c)-(pi)/(2)(d)(pi)/(2)

int_(-(pi)/(2))^((pi)/(2))[sin|x|-cos|x|dx

int_(-(pi)/(2))^((pi)/(2)) ( sin x )/( 2+ cos x )dx =".........."

[y] is the integral part of y, then int_((pi)/(2))^((3 pi)/(2))[2sin x]dx

int_((-pi)/(2))^((pi)/(2))sin^(7)x dx

The value of int_(-(pi)/(2)) ^((pi)/(2)) sin^(2) x cos x dx is

int_(-(pi)/(2))^((pi)/(2))(sin^(2009)x + x^(1009))dx

The value of int_((pi)/(4))^((pi)/(2))[sin x+[(2x)/(pi)]]dx where [.] denotes G.I.F.
