hi

how can i convert this below fourmula into fourier driver in anybody?

r(t)= L/(1- e*cos(w*t-phi))

L and e is constant, how can i get coef A and B from Tylor expansion?

Hi,

Your equation can be re-written like this:

r(t)= L- L*e*cos(w*t-phi));

So we can use AnyKinEqFourierDriver like this:

```
AnyKinEqFourierDriver driver =
{
AnyKinMeasureOrg& org = <SOMETHING YOU DEFINE>;
Type = cos;
Freq = w / (2.0*pi) ;
A = {{L, (-1)*L*e}};
B = {{0, -phi}};
};
```

And I attached an example of AnyKinEqFourierDriver which produce elliptical trajectory.

I hope this may help you.

Best regards,

Moonki
