" 8.If "tan^(3)x-1+(1)/(cos^(2)x)-3cot((pi)/(2)-x)=3" ,then the number of values of "tan x" is "

If tan^(-1)(sqrt(3)) +cot^(-1)x =(pi)/(2) , then find the value of x.

Let |{:(tan^(-1)x, tan^(-1)2x, tan^(-1)3x), (tan^(-1)3x, tan^(-1)x, tan^(-1)2x), (tan^(-1)2x, tan^(-1)3x, tan^(-1)x):}|=0 , then the number of values of x satisfying the equation is

If tan^(-1)(-sqrt(3))+cot^(-1)x=pi , then the value of x is :

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

If tan ^(-1) x + 2 cot ^(-1) x = (pi)/(3), then the value of x is

The solution set of inequality (cot^(-1)x)(tan^(-1)x)+(2-(pi)/(2))cot^(-1)x-3tan^(-1)x-3(2-(pi)/(2))>0 is (a,b), then the value of cot ^(-1)a+cot^(-1)b is

If tan^(-1)x+sin^(-1)x=-(2 pi)/(3) then the value of cos^(-1)x+cot^(-1)x is equal to

If tan^(-1)4+cot^(-1)x=(pi)/(2), then value of x is

3tan^(-1)x+cot^(-1)x=pi
