This page contains three views of the steps in the derivation: d3js, graphviz PNG, and a table.
Notes for this derivation:
Using the 2D equations of motion, show that projectile path is second order polynomial of the form y = a x^2 + b x + c
Clicking on the step index will take you to the page where you can edit that step.

4  substitute LHS of expr 1 into expr 2 



LHS diff is 0 RHS diff is (pdg1572  pdg4037)*(pdg1649*(pdg1572  pdg4037)*(pdg1649  1) + 2*pdg2958*(pdg9107 + pdg9431))/(2*pdg2958**2)
