poliastro2.math.special.stumpff_c2(psi)

Second Stumpff function.

For positive arguments:

\[c_2(\psi) = \frac{1 - \cos{\sqrt{\psi}}}{\psi}\]

poliastro2.math.special.stumpff_c3(psi)

Third Stumpff function.

For positive arguments:

\[c_3(\psi) = \frac{\sqrt{\psi} - \sin{\sqrt{\psi}}}{\sqrt{\psi^3}}\]
