sin105^(@)+cos105^(@)=?

Prove that : (i) "sin"105^(@)+cos105^(@)=(1)/(sqrt(2)) (ii) cos105^(@)+cos15^(@)="sin"75^(@)-"sin"15^(@)

sin15^(@)+cos105^(@)=?

Prove that: s in105^(@)+cos105^(0)=cos45^(@)

105^(2)

sin 105^(@) + cos 105^(@) = cos theta, then theta =

Prove that sin 105^(@) + cos 105^(@) = cos 45^(@)

Show that sin 105^(@) + cos 105^(@) =(1)/(sqrt(2))

sin75^(@)-sin15^(@)=cos105^(@)+cos15^(@)
