सिद्ध कीजिय की `sin 15^@ = (sqrt3 - 1)/(2sqrt2)`

Prove that sin15^@ = (sqrt3-1)/(2sqrt2)

sin^(-1)((sqrt(3)+1)/(2sqrt(2)))=

Prove that: sin15^(@)=(sqrt(3)-1)/(2sqrt(2))

Prove that: sin15^(@)=(sqrt(3)-1)/(2sqrt(2))

Show that sin^(2) 75^(@) - sin^(2) 15^(@) = (sqrt(3))/(2)

Prove that Sin15^(@)=(sqrt(3)-1)/(2sqrt(2))=Cos75^(@)

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

Prove that Sin105^(@)=(sqrt(3)+1 )/ (2sqrt(2))=Cos15^(@)

P.T (i) sin^2 52""1^@/2-sin^2 22""1^@/2=(sqrt3+1)/(4sqrt2) sin^2 52""1^@/2-sin^2 22""1^@/2=(sqrt3+1)/(4sqrt2)
