If `a=sin 30^@ and b=sin 30^@`, then

If a=sin30^(@) and b=sin30^(@), then

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

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

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.

If A = 60 ^(@) and B = 30 ^(@) , find the value of (sin A cos B+ cos A sin B)^(2) + (cos A cos B - sin A sin B )^(2)

By taking A = 90^@ and B = 30^@ , show that sin (A - B) = sin A cos B-cos A sin B.

Given that sin30^(@)=1//2 and cos 30^(@)=sqrt3//2 . Determine the values of sin 60^(@), sin 120^(@), sin 240^(@), sin 300^(@) , and sin (-30^(@)) .

Given that sin30^(@)=1//2 and cos 30^(@)=sqrt3//2 . Determine the values of sin 60^(@), sin 120^(@), sin 240^(@), sin 300^(@) , and sin (-30^(@)) .

Verify that : sin 60^@ = 2 sin 30^@ cos 30^@
