 Feb23 awarded Popular Question Jan10 comment How does Matlab, Maple, etcâ€¦solve algebraic and differential equations internally? I don't see anything in that link about differential equations are solved. Jan10 asked How does Matlab, Maple, etcâ€¦solve algebraic and differential equations internally?

Sep18 comment Intuition behind divergence? Cheers, I see it now, obviously there was a little bit more going on that I first thought. Would you mind posting the code for the flow diagrams so I could try out some variations myself to get a feel for them? Sep18 asked Intuition behind divergence? Sep15 awarded Popular Question Sep11 asked $\nabla \times \underline{v}$ - Results in a vector perpendicular to these two vectors? Sep11 comment $(1, 1) \cdot (6, 0) = 6?$ Intuition? Well it scales it, but what is the intuition behind the scaling? It seems we are no longer dealing with straightforward projection of $a$ onto $b$... Sep11 comment $(1, 1) \cdot (6, 0) = 6?$ Intuition? Well I already have that from above, it gives 6. I don't know what this means thought. Sep11 asked $(1, 1) \cdot (6, 0) = 6?$ Intuition?
