cot(tan^(-1)sqrt(3))

cot(tan^(-1)sqrt(3))

Evaluate cot (tan ^(-1) 3) .

Evaluate cot (tan ^(-1) 3) .

cot(tan^(-1)3)=(1)/(3)

The value of 2tan^(-1)(cos ec tan^(-1)x-tan cot^(-1)x) is equal to (a)cot ^(-1)x( b ) (cot^(-1)1)/(x) (c)tan ^(-1)x (d) none of these

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____
