Thanks for your investigation, however that does not adequately explain what’s happening. Try adding any other number except its contrapositive and it will correctly evaluate the integral - the evaluation is precise. ![image](https://canada1.discourse-cdn.com/flex031/uploads/desmos/original/2X/5/57cb5fe2ca0ce52917a5234f85ad3584f3d82cad.png) So while interesting, and perhaps revealing, I am not subsequently adding the contrapositive to test for zero-ness(which matters a lot in this context), simply taking the graph’s evaluation and placing it in the note - the values do not agree. For ill-behaved functions the phenomenon you’re talking about can happen, [when attempting to sum to zero](https://cl.desmos.com/t/integrals-1-0-0/2710/3), but that’s not what’s going on here. This function is simply composed of linear segments - in fact I’ve used this exact method for linear piece-wise integrand functions many times without issues, so I’m curious what is really going on here. edit: I completely agree that there’s a rounding issue(the reason the post is here at all!) but my main questions are: a) Why this happens at all for a linear function, as i’ve used this method many times before with no problems until now b) Why Desmos does not share consistent values between components(if value errors occur, I expect them to occur consistently) Thanks! --- _[View the full topic](https://cl.desmos.com/t/integration-error/3016)._
