It looks like an alternating series, so It's likely from a physics class involving electrostatic or maybe control systems. It also could be from a later calculus class where you're first introduced to alternating series like Taylor or Leibniz.
What issues? I have used for.. I don't even know. Feels like since my first smart phone. Never had issues.
I think most engineers have an understanding amongst each other, regardless of their specialty, we can all teach ourselves to problem solve. So many math and physics classes as an EE just to get to my core classes. It definitely a certain type of person to get through the thick of it.
Taycan is nicer inside and has a better feel driving but overall the Tesla wins me over. The space for my family, charging network, accessing everything on the screen, self driving and just Tesla's software overall, I think it really out does the Porsche
My brother in Christ, I have put several hours behind the taycan. The model Y is a better daily driver imo.
On the highway, I haven't had it fail or do anything weird in over a year. I watch the road, but keep my hands off. Daily commute, especially when there's traffic, is much less of a mental burden. I'm much more at ease to check my phone or look up a song. Local roads, I keep my hand a 3' o'clock while on the armrest. Not as liberal with diverting my eyes. Letting it do all the work makes driving better, it's definitely more relaxing.
