Find the value of cot (tan-1 α + cot-1 α). – InterviewSolution

1.

Find the value of cot (tan-1 α + cot-1 α).

Answer»

Given that: cot (tan^-1 + cot^-1 )

= cot (/) (since, tan^-1 x + cot^-1 x = /2)

= cot (180°/2) ( we know that cot 90° = 0 )

= cot (90°)

= 0

Therefore, the value of cot (tan^-1 α + cot^-1 α) is 0.
