SUMMARY

The discussion focuses on solving coupled differential equations related to Euler's formula in the context of homework equations. Specifically, the equations ω1 dot + Ωω2 = 0 and ω2 dot - Ωω1 = 0 are analyzed. The solution involves expressing ω1(t) as Acos(Ωt) and ω2(t) as Asin(Ωt), derived from Euler's identity e^(i * t) = cos(t) + sin(t)*i. The notes referenced provide a step-by-step explanation of this transformation.

Homework Equations



I know how to get:
ω1 dot + Ωω2 = 0
ω2 dot - Ωω1 = 0

The Attempt at a Solution



I know euler is e^(i * t) = cos(t) + sin(t)*i but not sure how the notes take it to :
ω1(t) = Acos(Ωt) , ω2(t) = Asin(Ωt)
