" (ii) "sin(A+B)=sin A cos B+cos A sin B

Prove that : sin(A- B) = sin A cos B -cos A sin B .

Prove that : sin(A + B) = sin A cos B + cos A sin B .

Given that sin (A+ B) = sin A cos B + cos A sin B , find the value of sin 75° .

If A= 30^@ and B= 60^@ , verify that : sin (A + B) = sin A cos B + cos A sin B .

If A = 30^(@) and B = 60^(@) , verify that sin (A + B) = sin A cos B + cos A sin B.

Using the fact that sin (A + B) = sin A cos B + cos A sin B and the differentiation, obtain the sum formula for cosines.

Prove by vector method that sin(A-B)=sin A cos B-cos A sin B and sin(A+B)=sin A cos B+cos A sin B

Prove that sin (A+B)= sin A cos B + cos A sin B.

Using the formula of sin(A-B)=sin A cos B-cos A sin B find the value of sin15^(@)

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