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. WebJan 31, 2024 · expand_trig(cos(2*t)) works (it gives 2*cos(t)**2 - 1). I also recommend using cos(t) instead of cos(1.0*t) , as SymPy will see them as different (e.g., cos(t) - cos(1.0*t) … canon photorecord とは
