sin15^(@)

sin 15^(@) + cos 105 ^(@) = ............ A) 0 B) 2 sin 15 ^(@) C) cos 15^(@) + sin 15^(@) D) sin 15^(@) - cos 15^(@)

The value of (cos 15^(@) - sin 15^(@))/(cos 15^(@) + sin 15^(@) is

(cos 15^(@) + sin 15^(@))/(cos 15^(@) - sin 15^(@)) =

|["cos"15^(@), "sin"15^(@)], ["sin"15^(@), "cos"15^(@)]|=?

sin 15^(@) =………….

sin 15^(@)=

(iii)Prove that (cos15^@-sin 15^@)/(cos 15^@+sin 15^@)=tan 30^@ .

sin 75^(@) + sin 15^(@) =

What is the values of sin 15^(@)sin75^(@) ?
