Are there any helpful constellations of 2 angles or sin/cos of the same angle, as in "sin(60) + cos(30) = 1"? Yeah, sin(90) + cos(0) = 1 and vice versa, but apart from that?
I know sin, cos and tan rules, I'm just looking for easier equation solving when calculating forces, where you constantly have huge equations.
Thanks in advance!
+23247 The examples that you gave can be generalized to: sin(x) = cos(90° - x).
