| Hello! I'm new to mathematica and I'm having some trouble properly setting up a test case. I have an equation G as well as its time derivative Gdot, I want to take the derivative of G, then plug in numerical values and compare that to numerical... |
| By components I mean the solution is given in terms of r1, r2 and r3. Is there a way to get it into vector format. Essentially is there a way to take the derivative of `a = -mu/r^3 rvec` and get `mu/r^3 [3 rhat rhat^T - I ]` out, in exactly this... |
