RE: Plus42 Equations, Preview Release
(05-09-2022 08:40 AM)Thomas Okken Wrote: The integrator doesn't solve the equation, it just evaluates it, and evaluating an equation with a top-level = sign means evaluating its left- and right-hand sides and subtracting the latter from the former. So if you're integrating Y=X^2 with integration variable Y, you're integrating Y-X^2, where X will be whatever value it happens to be when you start the integration. Out of curiosity, what happens under the hood differently when integrating the same equation after plotting it? I get the ‘rights answer when I do that. An easy workaround for this has been to set the LHS to zero and reverse LLIM and ULIM. |
