`tan^(-1) (1) + sin^(-1) (1) + cos^(-1) (1)`

The value of (cot^(-1)(-sqrt(3))+sec^(-1) (1)+tan^(-1)(-1))/(sin^(-1)(1//2) +cos^(-1)(-(sqrt(3))/(2)) +"cosec"^(-1)(-1)) is :

6. Find the value of tan^(-1) (1) + cos^(-1)(-1/2)+ sin^(-1)(-1/2)

tan ^(-1)(1) + cos^(-1)(1/sqrt2) + sin^(-1)(1/2)

tan ^ (- 1) ((1 + sin x) / (cos x))

tan ^ (- 1) ((1 + sin x) / (cos x))

tan (sec ^ (- 1) x) = sin (cos ^ (- 1) ((1) / (sqrt (5))))

(1/y^2 \ ((cos(tan^(-1) y) + y sin(tan^(-1) y))/(cot(sin^(-1) y) + tan(sin^(-1) y)) )^2 + y^4)^(1//2) takes value

Find the value of: tan^(-1)(1)+cos^(-1)(-(1)/(2))+sin^(-1)(-(1)/(2))
