HELP ASAP Find the exact value of sin15° by using a sum or difference formula. BRANLIEST

The exact value of sin 15° is .

Solution:

45 – 30 = 15

sin 15° can be written as sin (45° – 30°).

Using trigonometric difference formula:

sin(A – B) = sin A cos B – cos A sin B

sin (45° – 30°) = sin 45° cos 30° – cos 45° sin 30°

The value of sin 45° =

The value of cos 30° =

The value of cos 45° =

The value of sin 30° =

Substitute these values, we get  

Hence the exact value of sin 15° is .

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
