If `int(x^(2)-4)/(x^(4)+9x^(2)+16)dx=tan^(-1)f(x)+c`, then the value of f(4) is less than or equal to

Evaluate : int(x^(2)-4)/(x^(4)+9x^(2)+16)dx

If int(5x^(4)+4x^(5))/((x^(5)+x+1)^(2))dx=f(x)+C , then the value of (1)/(f(1)) is

If f(x)=inte^(x)(tan^(-1)x+(2x)/((1+x^(2))^(2)))dx,f(0)=0 then the value of f(1) is

If int(sin2x)/(sin^(4)x+cos^(4)x)dx=tan^(-1)[f(x)]+c , then f(pi/3)=

int(1)/((x+1)[(x+1)^(4)+1])dx=(1)/(4)*log f(x)+c then the value of f(x) at x=1 is

If f(x)=(4cos^(4)x-2cos^(2)x-(1)/(2)cos4x+2sin^(2)x-x^(9))^((1)/(9)) then the value of f(f(2)) is equal to
