`tan^(- 1)a x+1/2sec^(- 1)b x=pi/4`

tan^(-1)ax+(1)/(2)sec^(-1)bx=(pi)/(4)

If tan^(-1)(a/x) + tan^(-1)(b/x) =pi/2 , then: x=

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

Range of f(x)=sin^(-1)x+tan^(-1)x+sec^(-1)x is (a) ((pi)/(4),(3 pi)/(4))( b) [(pi)/(4),(3 pi)/(4)]( c) {(pi)/(4),(3 pi)/(4)}(d) none of these

If tan^(-1)(a/x) + tan^(-1)(b/x) = pi/2 , then: x=……

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