` 2 Tan^(-1)(1/2) + Sin^(-1)(3/5)`=

cos^(-1)((63)/(65))+2tan^(-1)((1)/(5))=sin^(-1)(3/5)

Prove that tan^(-1) (1/4) + tan^(-1) (2/9) = 1/2 sin^(-1) (4/5)

Prove that tan^(-1) (1/4) + tan^(-1) (2/9) = 1/2 sin^(-1) (4/5)

Let alpha=2tan^(-1)((1)/(2))+(sin^(-1)3)/(5) and beta=sin^(-1)((12)/(13))+cos^(-1)((4)/(5))+cos^(-1)((16)/(63)) be such that2sin alpha and cos beta are roots of the equation x^(2)-px+q=0, then (p-q) is

If A = 9 tan^(-1) (sqrt2 - 1) and B = 3 sin^(-1)(1/3)+sin^(-1)(3/5) then

If A = 2 tan^(-1) ( 2 sqrt2 -1) " and " B = 3 sin ^(-1) ( 1/3) + sin^(-1) ( 3/5) ", then show " A gt B .

If 2"tan"^(-1)(1)/(5)-"sin"^(-1)(3)/(5)= -"cos"^(-1)(63)/(lambda , then lambda=

If 2"tan"^(-1)(1)/(5)-"sin"^(-1)(3)/(5)= -"cos"^(-1)(9lambda)/(65) , then lambda=
