Sorry for the dumb question, but I'm not involved in math. I need to reverse the following formula, to calculate $\alpha$:
$$a = b(\alpha + \sin \alpha)/c$$
So I have:
$$(\alpha + \sin \alpha)=ac/b = K$$
Since $a$, $b$, $c$ are constant, I put equal to $K$.
$\alpha$ is measured in radians. I need to find the value of $\alpha$ (in radians or degree).
Thanks to all!!
