x का मान ज्ञात कीजिए यदि `tan^(-1)(x)^(-1) = cot^(-1)((4)/(x))`

Solve for x tan^(-1)(x-1)=cot^(-1)((4)/(x))

tan^(-1)(cot4x)

dy/dx का मान ज्ञात कीजिए यदि x=2at,y=at^2

tan^(-1)(cot x)+cot^(-1)(tan x)

cot(tan^(-1)x+cot^(-1)x)

tan^(-1)(cot x)-tan^(-1)(cot2x)=

Prove that tan(cot^(-1)x)=cot(tan^(-1)x)

If tan^(-1)x+tan^(-1)y=(4 pi)/(5), find cot^(-1)x+cot^(-1)y

If tan^(-1)x+tan^(-1)y=(pi)/(4) , then cot^(-1)x+cot^(-1)y=

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
