A e has o investing large teams of people testiit carefully, aton, but din't soin practice. It turns out that you can integrate a lot, o lot in wide glasses of for s just by alementing al wodslewards. And mathematica, laly as the and farkas wolfra i th they manage to do that. That's lorifi for alotto work. Ah, you can make it very useful in practice. For example, for a polyno mel, it's easy, handb do it, right? And then you can add some trigermentary function.
