Simplify equation

samedi 1 février 2014

1. The problem statement, all variables and given/known data



Dear all,



I want to simplify an equation using Taylor series expansions but I do not know how to do it.

Can someone help me?







2. Relevant equations

The euqation is as follows:



X = [itex]e \cos\theta + \sqrt{(R^2 - e^2 \sin^2 \theta)}[/itex]



X = distance

e = eccentricity

theta = angle

R = radius



3. The attempt at a solution

I think the above equation can be simplified using Taylor series expansion in terms of [itex]\sin^2 \theta[/itex].
