`y = tan^(- 1)(cotx) + cot^(- 1)(tanx), pi/2 < x < pi` then `dy/dx`

Solve: tan^(-1)(cotx)+cot^(-1)(tanx)= pi/4

Prove that , tan^(-1)(cotx)+cot^(-1) (tan x) = pi-2x

Prove that , tan^(-1)(cotx)+cot^(-1) (tan x) = pi-2x

If y = tan^-1(cotx) + cot^-1(tanx) , then prove that : dy/dx + 2 = 0

(d)/(dx)[tan^(-1)(cotx)+cot^(-1)(tanx)]=

If y=tan^-1(cotx)+cot^-1(tanx), find (dy)/dx .

Tan^(-1)(cotx)-Tan^(-1)(cot2x)=

tan^(-1)(cotx)+cot^(-1)(tanx) = ______ (0ltxltpi/2)

If x ne npi, x ne (2n+1)pi/2 , n in Z , then : sin^(-1)((sin^(-1) (cos x) + cos^(-1) (sinx))/(tan^(-1) (cotx)+cot^(-1) (tanx))) =
