Summary
[edit]DescriptionTrig-addition-laws.svg |
English: A geometric diagram for proof of the addition formula for cosines and the addition formula for sines. This is a standard geometric construction for those proof. The labels on this diagram match the labels on the video proving the addition formula at the CC-SA-BY-3.0 licensed trigonometry videos at www.khanacademy.org so that it can be more easily used in conjunction with that free courseware. |
