sin(45)sin(30)

<-- Enter special trig expression or identity

Using the Product to Sum Formula for Trig, Calculate Sin(45°)Sin(30°)

There exists a special identity to simplify this below:
Sin(u)Sin(v) =Cos(u - v) - Cos(u + v)
2

In this case, u = 45 and v = 30
Sin(45)Sin(30) =Cos(45 - 30) - Cos(45 + 30)
2

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

Sin(45)Sin(30) =0.49 - 0.3
2

Sin(45)Sin(30) =0.19
2

Sin(45)Sin(30) = 0.6
