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.
