Nicolas Zea Posted November 26, 2011 Report Share Posted November 26, 2011 The objective of this task is the construction of mathematical models of the orbits of the solar system planets and moons of Jupiter. The models will be used topredict the location of other moons, or in the case of the solar system, asteroids.A monk of Sicily, during the winter of 1800 or 1801, an asteroid discovered using a similar model. Gauss, a famous mathematician of great ability, calculated its orbit and the asteroid Ceres was discovered shortly after.Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluton Asteroid X 1 2 3 4 6 7 8 9 10 5 Y 57.9 108.2 149.6 227.9 778.3 1249 2871 4504 5914 T So i should found a model or an equation that describes this, but the problem is that when I graph i obtein an exponencial graph and in the moment of transformed into a linear graph it doesn't describe a constant behavior. Have you any idea of the model? Reply Link to post Share on other sites More sharing options...

dessskris Posted November 27, 2011 Report Share Posted November 27, 2011 wow! this is a very old IA task! you're doing it for practice yeah?exponential doesn't really fit well. cubic fits quite okay, but logistic fits best. if you have TI, use it to find the logistic regression. it looks great in my TI, fits almost perfectly!@rFumachi basically x is from 1 to 10, y is from 57.9 to 5914 and each point corresponds to a planet from Mercury to Pluto Reply Link to post Share on other sites More sharing options...
rFumachi Posted November 27, 2011 Report Share Posted November 27, 2011 Then that means there are ten X values and just 9 Y values . Well anyway I think you already helped Reply Link to post Share on other sites More sharing options...
dessskris Posted November 27, 2011 Report Share Posted November 27, 2011 oh, the value of y for x=6 (Asteroid) is empty it's being asked, to be deduced from the model. Reply Link to post Share on other sites More sharing options...
