x→1−x;Let A bee the integral  =∫_0 ^1 (dx/((1+e^(−2+4x) )(5+2x−2x^2 )))⇒  2A=∫_0 ^1 [(1/((5+2x−2x^2 ))).((1/(1+e^(−2+4x) ))+(1/(1+e^(2−4x) )))dx  =∫_0 ^1 (dx/(5+2x−2x^2 ))..easy from Hear

x1x;LetAbeetheintegral=01dx(1+e2+4x)(5+2x2x2)2A=01[1(5+2x2x2).(11+e2+4x+11+e24x)dx=01dx5+2x2x2..easyfromHear

King′s Rule  ∫_a ^b f(x)dx=∫_a ^b f(a+b−x)dx

KingsRulebaf(x)dx=baf(a+bx)dx
