Example 3 result
For the example 3, I don't find the same result as written. I find : $$\int \frac{dt}{1+\beta\cos t} = 2(1-\beta^2)^{-1/2}\arctan\left[\frac{(1-\beta)\sin t}{\sqrt{1-\beta^2}(1+\cos t)}\right] + c.$$

I have added the key points for a better understanding of the calculation. Maybe I'm wrong. Or maybe not. I don't know... If someone could werify it... --Lostinthiswhirlpool (talk) 23:31, 12 October 2019 (UTC)


 * This was an error (confirmed by a math teacher on the French wikipedia), I have modified the result. --Lostinthiswhirlpool (talk) 08:23, 13 October 2019 (UTC)
