`tan^(-1)(3x+7)+2tan^(-1)(1/2)=(pi)/(2)`

tan^(-1)(x/2)+tan^(-1)(x/3)=(pi)/(4)

2tan^(-1)(1/2)-tan^(-1)(1/7)=(pi)/(4)

Q.solve for x ,tan ^(-1)(2x)+tan^(-1)(3x)=(pi)/(4)

prove that 2(tan^(-1)1)/(3)+(tan^(-1)1)/(7)=(pi)/(4)

Solve for x:tan^(-1)3x+tan^(-1)2x=(pi)/(4)

If tan^(-1)(1+x)+tan^(-1)(1-x)=(pi)/(6), then prove that x^(2)=2sqrt(3).

tan^(-1)x+tan^(-1)(1)/(x)={[(pi)/(2), if x>0-(pi)/(2), if x<0

tan^(-1)(1/3)+(1)/(2)tan^(-1)(1/7)=(pi)/(8)

Prove the following: 4tan^(-1)(1)/(5)-tan^(-1)(1)/(70)+tan^(-1)(1)/(99)=(pi)/(4)2tan^(-1)(1)/(5)+sec^(-1)(5sqrt(2))/(7)+2tan^(-1)(1)/(8)=(pi)/(4)

Statement-1: sin^(-1)tan((tan^(-1))x+tan^(-1)(1-x))] =(pi)/(2) has no non zero integral solution Statement-2: The greatest and least values of (sin^(-1)x)^(3)+(cos^(-1)x)^(3) are (7pi)^(3)/(8) and (pi)^(3)/(32) respectively
