`tan^(-1)x^(2)`

For real numbers alpha, beta, gamma and delta , if int((x^(2)-1)+tan^(-1)((x^(2)+1)/(x)))/((x^(4)+3x^(2)+1)tan^(-1)((x^(2)+1)/(x)))dx = alpha log_(e)(tan^(-1)((x^(2)+1)/(x)))+beta "tan"^(-1)((gamma(x^(2)-1))/(x))+delta tan ((x^(2)+1)/(x))+C where is an arbitrary constant, then the value of 10(alpha+betagamma+delta) is equal to........

tan^(-1)(2+x)+tan^(-1)(2-x)=tan^(-1)((2)/(3))

Solve: tan^(- 1) (2+x) + tan^(- 1) (2 -x ) = tan^(-1) 2/3

Solve for x : tan^(-1)(2+x)+tan^(-1)(2-x)=tan^(-1)2/3 , where x sqrt(3)

If x gt 1 then 2tan^(-1)x - tan^(-1) ((2x)/(1-x^(2))) =______.

Prove the following: 2tan^(-1)x=tan^(-1)((2x)/(1-x^(2))),-1ltxlt1

Solve tan^(-1)x +"tan"^(-1) (2x)/(1-x^(2))=(pi)/(2) .

Solve : tan^(-1)x+tan^(-1)((2x)/(1-x^2))=pi/2

Solve : tan^(-1) x + tan^(-1)( (2x)/(1-x^2)) = pi/3

Solve : tan^(-1) x + tan^(-1)( (2x)/(1-x^2)) = pi/3
