I have a non-linear ODE that I need to linearise.

I could go about linearising the trig terms using Taylor series...but not sure about a square root of the form:

$$\sqrt{(A+C)^2 + B -2 * \cos (\alpha - \theta)}$$

Thanks.

    Is $\theta$ your variable?2010-12-09

    Could you do a change of variables and make $\sqrt{(A+C)^2+B-2*\cos(\alpha-\theta)}$ a new variable?2010-12-09

    Maybe giving the actual nonlinear ODE might yield answers more useful to you?2010-12-10
