WebJul 29, 2015 · I think Augustin was answering a much more general question. In two dimensions, where we have "cosine" already defined, from trigonometry, one can show that the "dot product", defined in some other way, is equal to the lengths of the two vectors times the cosine of the angle between them. WebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.
