" (D) "int_(0)^(oo)(sin^(3)x)/(x)dx

If int_(0)^(oo)(sinx)/(x)dx=k , then the value of int_(0)^(oo)(sin^(3)x)/(x)dx is equal to

underset equal to int(sin x)/(x)dx=(pi)/(2), then int_(0)^(oo)(sin^(3)x)/(x)dx is

underset equal to int(cos x)/(x)dx=(pi)/(2) then int_(0)^(oo)(cos^(3)x)/(x)dx is

Prove that int_(0)^(oo) (sin^(2)x)/(x^(2))dx=int_(0)^(oo) (sinx)x dx

If int _(0)^(oo) (cos x)/(x ) dx =pi/2 , then int _(0)^(oo) (cos ^(3) x )/(x) dx is equals to:

int_(0)^(oo)(a^(-x)-b^(-x))dx

int_(0)^(oo)(a^(-x)-b^(-x))dx=

int_(0)^(oo)(x)/(1+x^(4))dx=

int_(0)^(oo)(sin^(2)x)/(x^(2))dx must be same as int_(0)^(oo)(sin x)/(x)dx (b) (int_(0)^(oo)(sin x)/(x))^(2)int_(0)^(2)(cos^(2)x)/(x^(2))(d) none of these
