An artistic engineer & humanitarian at heart. As a technology architect, I create solutions which take the confusions out of things. I love to help people.

comment Calculate base and coefficient for power curve through 3 non-linear points
Thanks. I had another problem that apparently also requires Newton's method to solve. I have a personal friend who's up on them. Time to speak to him. I appreciate your time & help.

Thanks for your answer. So basically, the bottom line is there isn't a straightforward formula. My current algorithm takes about 131 steps to get the result accurate to the maximum 64 bit floating point resolution, guaranteed.

Whatever the value of B, it results in x mapping to the second bucket (#1, #0 being first).

$r$ is part of the unknown formula that I need in order to find $b$ and $R$. Yes, I could scrap $r$ and call it $B$. The graph should be stepped, but I was merely trying to show it's curved. Maybe I should remove it.

I hope my edits help clarify the question. $r=B$

Why the downvote? Only useful with explanation.
