sin(45)cos(30)

<-- Enter special trig expression or identity

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

There exists a special identity to simplify this below:
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) =0.94 + 0.56
2

Sin(45)Cos(30) =5
2

Sin(45)Cos(30) = 0.75
