Butch Posted June 22, 2021 Share Posted June 22, 2021 In this desmos graph: https://www.desmos.com/calculator/f607tsq5ux I need to find max for the elliptical paths of rab and rcd so that I can determine the foci... I have researched on the web finding max of a function, but just cannot seem to get my head around it. Would greatly appreciate some help. Link to comment Share on other sites More sharing options...
mathematic Posted June 22, 2021 Share Posted June 22, 2021 It looks like the min and max occur when sin = 0 (0 or 180). Link to comment Share on other sites More sharing options...
