Calculate Sin(45°) + Sin(30°)
The Sum to Product Formula Formula states the following:
sin(u) + sin(v) = 2sin(a)cos(b)a and b are defined below:
| a = | u + v |
| 2 |
| a = | 45 + 30 |
| 2 |
| a = | 75 |
| 2 |
a = 37.5
| b = | u - v |
| 2 |
| b = | 45 - 30 |
| 2 |
| b = | 15 |
| 2 |
b = 7.5
With a = 37.5° and b = 7.5°, we have
sin(45) + sin(30) = 2sin(37.5)cos(7.5)
sin(45) + sin(30) = 2(0)(1)
sin(45 + 30) = 0
