`sin^(- 1)1/(sqrt(17))+cos^(- 1)9/(sqrt(85))=tan^(- 1)1/2`

If sin^(-1)[(1)/(sqrt(10))]+sin^(-1)[(2)/(sqrt(85))]+sin^(-1)[(4)/(sqrt(1105))]+....oo= ,then find the value of tan alpha

Find the value of : tan^(-1) ((-1)/(sqrt(3)))+cos^(-1)((-sqrt(3))/2)+sin^(-1)(1/2)

Prove that: sin^(-1)((3)/(5))+cos^(-1)((5)/(sqrt(26)))=tan^(-1)((19)/(17))

Evaluate: tan^(- 1)(-1/(sqrt(3)))+tan^(- 1)(-sqrt(3))+tan^(- 1)(sin(-pi/2))

cos^(-1)(1/4)=sin^(-1)sqrt(1-1/16)=sin^(-1)((sqrt(15))/4) =tan^(-1)(sqrt(15))

Evaluate the value of tan^(-1) (-sqrt(3)) +cos^(-1) (1/(sqrt(2))) + sin^(-1) (-(sqrt(3))/2)

Find the value of sin^(-1)(-(sqrt(3))/(2))+cos^(-1)((1)/(2))+tan^(-1)(-(1)/(sqrt(3)))

The value of sin ^(-1) (-(1)/(sqrt2)) + cos ^(-1) (-(1)/(2)) - tan ^(-1) (-sqrt3) + cot ^(-1) (-(1)/(sqrt3)) is

The value of sin ^(-1) (-(1)/(sqrt2)) + cos ^(-1) (-(1)/(2)) - tan ^(-1) (-sqrt3) + cot ^(-1) (-(1)/(sqrt3)) is

tan^(-1)(2)=sin^(-1)(2/(sqrt(5)))=cos^(-1)(1/(sqrt(5)))
