`sin theta+sin(120^(@)+theta)-sin(120^(@)-theta`

sin theta + sin (120^(@) + theta ) + sin ( theta - 120^(@)) =

If a sin theta =b sin (120^(@) +theta) =c sin (240^(@) +theta), then the value of (ab+ bc+ ca) is-

The maximum value of sin^(2)(120^(@)+theta)+sin^(2)(120^(0)-theta) is 1/2b3/2c.1/4d.3/4

sin (60^(@) + theta) - sin ( 60^(@) - theta ) = sin theta.

Maximum and minimum value of sin^(2)(120^(@) + theta ) + sin^(2) (120^(@) - theta ) are

Assertion (A):cos^(2)theta+cos^(2)(60^(@)-theta)+cos^(2)(60^(@)+theta)=(3)/(2)sin alpha-sin(120^(@)-alpha)+sin(120^(@)+alpha)=0

Assertion (A):cos^(2)theta+cos^(2)(60^(@)-theta)+cos^(2)(60^(@)+theta)=(3)/(2)sin alpha-sin(120^(@)-alpha)+sin(120^(@)+alpha)=0

If cot theta = 8//15 and theta does not lie in the first quadrant , then cos (30^(@) + theta ) + sin (45^(@) - theta ) + cos(120^(@) + theta ) =

(cos theta)/(sin(90^(@)+theta))+(sin(-theta))/(sin(180^(@)+theta))-(tan(90^(@)+theta))/(cot theta)

Find the value of sin theta+sin(theta+120^(@))+sin(theta+240^(@))
