The value of `(-2+x)/(4+x)=2`

fx be real,prove that the value of (2x^(2)-2x+4)/(x^(2)-4x+3) cannot lie between -7 and 1

If f(x)=-int_(0)^(x) log (cos t) dt, then the value of f(x)-2f((pi)/(4)+(x)/(2))+2f((pi)/(4)-(x)/(2)) is equal to

If x is real then the value of (x^(2)-3x+4)/(x^(2)+3x+4) lies in the interval

The value of int _(2)^(4) { |x-2|+|x-3|} dx is

Given (x)/(x^(2)+3x+1)=a(a!=0) then value of (x^(2))/(x^(4)+3x^(2)+1) is

If x-(1)/(x)=(1)/(2), then write the value of 4x^(2)+(4)/(x^(2))

The value of int(x^(2)+1)/(x^(4)-x^(2)+1)dx is

The value of int ( ( x ^ 2 + 1 )) /( x ^ 4 + x ^ 2 + 1 ) dx is
