# Drawing with latex

I'm writing my final year mathematics project in latex and am deriving Keplers laws of planetary motion, i need some diagrams to explain the geometry I am using. I have already used tikz to draw an the areas for Keplers second law, from a model i found online, I am not entirely sure how to use the program. Is there an book or online guide to help me draw the diagrams? Thanks.

Welcome to TeX.sx. The manual is the obvious thing to mention, it starts with several tutorials. See tex.stackexchange.com/questions/9116 and tex.stackexchange.com/questions/15779 for some additional resources. – Torbjørn T. Jan 7 '14 at 12:08
