If `sin(A+B)=sinAcosB+cosAsinB` and `cos(A-B)=cosAcosB+sinAsinB`, find the values of `(i) sin75^(@)` and `(ii) cos15^(@)`.

If sin (A-B)=sin A cos B-cos A sin B and cos (A - B) = cos A cos B + sin A sin B . find the values of sin 15^@ and cos 15^@.

Find the value of :(i)sin75^(@) (ii) tan15^(@)

Find the values of the following: (i) sin75^(@) (ii) cos15^(@)

Given that sin(A+B)=sin A cos B+cos A sin B, find the value of sin75o.

Using the formula cos (A+B) = cosA cosB -sin A sin B . find the value of sin 15^(@) .

Find the value of sin 15^@+ cos 15^@

Find the value of (sin75^(@)+sin15^(@))/(cos75^(@)+cos15^(@)) :

The value of cos15^(@)-sin15^(@) is
