Answer:

0

Step-by-step explanation:

We know

tan^-1 a + cot^-1 a = π/2

so, question simplifies to cot(π/2)

cot(π/2)=0

Given   :  cot (tan⁻¹ a + cot⁻¹a)

To find :    मान ज्ञात कीजिए

Solution:

 cot (tan⁻¹ a + cot⁻¹a)  

माना  a  = tanx

=  cot (tan⁻¹ (tanx) + cot⁻¹(tanx))

हमें ज्ञात है की tanx = cot(π/2 - x)

= cot (tan⁻¹ (tanx) + cot⁻¹(cot(π/2 - x)))

= cot ( x + π/2 - x )

= cot (π/2 )

= 0

cot (tan⁻¹ a + cot⁻¹a)  का मान = 0
