# Good books for undergraduates to understand Milankovitch cycles

Forgive me for wierd expression becaus English is not my native tongue. I want some suggestion for books about the math and physics about how Milankovitch cycles were calculated. i.e. How eccentricity, tilt, precession cycles are determined. Maybe textbook on celestial mechanics will help but I do not know which book I should start.

Alternatively, if you just want to determine the cycles yourself, it would be much much easier to just numerically solve Newton's equations $\ddot{x}_i=\sum_j \frac{G m_i}{x_{ij}^3} \vec{x}_{ij}$ and do a Fourier transform :)
