Problem
From the data in the text, make an estimate of the lower mass limit of the compact companion in V404 Cyg by setting the orbital inclination i=90°. Refer to Appendix G in order to make a rough determination of the mass of the K0 IV companion. Why does your calculation result in a lower limit? What further information would be required to make a more precise determination?
