Well i know that an inflection point is where the curve changes its concavity.(adsbygoogle = window.adsbygoogle || []).push({});

But i dont really understand the conditions for it.

It says that second derivative should be zero(but thats not sufficient). I understand this. Second derivative being zero is not sufficient, example is y =x^4. So further condition is that some of the following odd derivatives should be zero which i don't understand

What's with the odd derivative? I don't get the intuition
