How to add cosines

We proved the sine addition formula; now we're going to prove the cosine addition formula. 1. cos ⁡ ( α + β ) = cos ⁡ ( α ) cos ⁡ ( β ) − sin ⁡ ( α ) sin ⁡ ( β ) {\displaystyle \cos(\alpha +\beta )=\cos(\alpha )\cos(\beta )-\sin(\alpha )\sin(\beta )} Before we do that we will talk about subtraction formulae. Now to … Se mer The proof looks mighty similar to the proof for sin ⁡ ( α + β ) {\displaystyle \sin(\alpha +\beta )} . We can in fact derive one from the other without using a diagram at all. Now it is your turn to practice deriving new formulas from old ones: … Se mer Nettet1) Cosine addition laws: cos ( ω t) + 2 ( cos ( ω t) cos ( π 4) − sin ( ω t) sin ( π 4)) + 3 ( cos ( ω t) cos ( π 2) − sin ( ω t) sin ( π 2)) = cos ( ω t) ( 1 + 2) − sin ( ω t) ( 3 + 2) 2) Phasors …
