tan^(-1)x=(3)/(4),vec at cos^(-1)x" an did "

If tan^(-1)(1)/(4)+tan^(-1)(2)/(9)=(1)/(2)cos^(-1)x then x is equal to

Solve the following equation for x:cos(tan^(-1)x)=sin((cot^(-1)3)/(4))tan(cos^(-1)x)=sin((cot^(-1)1)/(2))

Solve the following equation for x : "cos"(tan^(-1)x)=sin(cot^(-1)(3/4)) , tan(cos^(-1)x)=sin(cot^(-1)(1/2))

If tan ^(-1)x=(3)/(4), then find the value of cos^(-1)x

If x != 0 , then tan((pi)/4 + 1/2 cos^(-1) x) + tan ((pi)/4 - 1/2 cos^(-1) x) = ......

If tan^(-1)x=(pi)/(4)-tan^(-1)((1)/(3)) , then x is

If tan^(-1)x=(pi)/(4)-tan^(-1)((1)/(3))then x is

If tan^(-1)(x+(3)/(x))-tan^(-1)(x-(3)/(x))=tan^(-1)(6)/(x) then the value of x^(4) is
