(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex] \frac{x^2}{a^2}+\frac{y^2}{a^2(1-e^2)} =1[/tex]

The ellipse meets the major axis at a point whose abscissa is [tex]\lambda[/tex]. Find lim [tex]\theta ->0[/tex].

2. Relevant equations

Parametric coordinates of an ellipse: (acosx,bsinx)

3. The attempt at a solution

The abscissa is the x coordinate and here the x axis is the major axis as [tex] b^2 = a^2(1-e^2)[/tex]. Therefore, [tex]\lambda =acos\theta[/tex].

Which would give you [tex]a[/tex]. The answer, however, should be ae... dunno how...
