cot((sin^(-1)1)/(sqrt(5))+(sin^(-4)2)/(sqrt(5)))

The value of alpha so that sin^(-1)((2)/(sqrt(5))) , sin^(-1)((3)/(sqrt(10))) and sin^(-1)alpha are the angles of a Delta is

sin^(-1)(1/sqrt5)+cos^(-1)(3/sqrt(10))

The value of sin^(-1)((3)/(sqrt(73)))+cos^(-1)((11)/(sqrt(146)))+cot^(-1)sqrt(3) is k pi then (1)/(k)

The value of sin^(-1)((3)/(sqrt(73)))+cos^(-1)((11)/(sqrt(146)))+cot^(-1)sqrt(3) is (A)(5 pi)/(12) ( textrmB ) (17 pi)/(12) (C) (7 pi)/(12) (D) None of these

The value of sin^(-1)((3)/(sqrt(73)))+cos^(-1)((11)/(sqrt(146)))+cot^(-1)sqrt(3) is a.(5 pi)/(12) b.(7 pi)/(12) c.(7 pi)/(12) d.none of these

The value of alpha such that sin^(-1)(2/(sqrt(5))),sin^(-1)(3/(sqrt(10))),sin^(-1)alpha are the angles of a triangle is

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

If alpha=sin(sin^(-1)( 1/sqrt3)/(3)),beta=cos(cos^(-1)((1)/(sqrt(5)))-sin^(-1)((2)/(sqrt(5)))) then (beta^(2))/((3 alpha-4a^(3))^(2)) is
