Let `I=int_0^(pi/2)(sinx/x)dx`, then

If int_0^pi x f(sinx) dx=A int_0^(pi/2) f(sinx)dx , then A is (A) pi/2 (B) pi (C) 0 (D) 2pi

If int_(0)^(pi)xf(sinx)dx=A int_(0)^(pi//2) f(sinx)dx , then A is

Let I=int_(0)^(24pi){sinx}dx then the value of 2I is equal to (where, {.} denotes the fractional part function)

Let I=int_(0)^((pi)/(2))((sin x)/(x))dx, then

int_0^(pi/2) (sinx)/(1+Cos^2x)dx

int_0^(pi/2) (Cosx - Sinx)dx

int_0^(pi/2) cosx/(1+sinx)dx

int_(0)^(pi//2)(x)/(sinx+cosx)dx .

int_(0)^(2pi)(sinx+cosx)dx=

int_(0)^(2pi)|sinx|dx=?
