sin(45)cos(30)

sin(45)cos(30)

Using Product to Sum Formula

The Product to Sum Formula states the following:

Use a trig identity:

Sin(u)Cos(v)  =	Sin(u + v) + Sin(u - v)
	2

In this case, u = 45 and v = 30

Sin(45)Cos(30)  =	Sin(45 + 30) + Sin(45 - 30)
	2

Sin(45)Cos(30)  =	Sin(75) + Sin(15)
	2

Sin(45)Cos(30)  =	0.96592582590194 + 0.25881904481356
	2

Sin(45)Cos(30)  =	1.2247448707155
	2
