sin ^(-1) "" (1)/(sqrt(5))+cot ^(-1) 3= (pi)/(4)

Solve : cos(tan^(-1)x)=sin(cot^(-1)""(3)/(4))

If: cos(tan^(-1)x)=sin (cot^(-1).(3)/(4)), then : x =

Solve cos(tan^-1x) = sin(cot^-1 (3/4))

tan ^(-1) (cot x) + cot ^(-1) (tan x) =(pi)/(4)

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

Which of the following quantities is/are positive? "cos"(tan^(-1)(t a n4)) (b) "sin"(cot^(-1)(cot4)) "tan"(cos^(-1)(cos5)) (d) "cot"(sin^(-1)(sin4))

Which of the following quantities is/are positive? (a) "cos"(tan^(-1)(t a n4)) (b) "sin"(cot^(-1)(cot4)) "tan"(cos^(-1)(cos5)) (d) "cot"(sin^(-1)(sin4))

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

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