I need to convert the Keplerian orbital elements to the equinoctial elements and then use the converted elements"equinoctial" in the function "d" below. To do this, first, I converted the Keplerian elements to equinoctial elements (a,h,k,p,q,lamda) using the formula in the attached picture, BUT I need to know what is the equinoctial elements that correspond to each of e,i,w,omega so that I can replace each keplerian elements in the function "d" with the equinoctial element.

d= Sin[omega]* Cos[w]2 +[w] + Cos[omega] Cos[i] Sin[w - Omega]

    $\begingroup$ Are you sure that the $w$ summand in the middle is correct? Also, are there variables $w$, $omega$, and $Omega$? $\endgroup$ – aventurin Dec 31 '18 at 15:48

    $\begingroup$ Its not very clear what you want. Perhaps you want to calculate the keplerian elements from a, h, k, p q and lambda $\endgroup$ – James K Dec 31 '18 at 18:09
