Back when I had to enter math answers into a computer, it would count me wrong for sight deviations on a right answer. If I had a random space bar or whatever it was wrong. I can't imagine a computer checking for an answer like this. What the fuck am I even looking at!?
It’s some sort of alternating harmonic series, it looks like Gregory’s series as a base multiplied by sub junk and obfuscated for an undergrad homework problem to me.
As someone who has done this over the years, 2007 version was horrible (as you described), 2015 was normal, 2024 version as you see will literally give you the answer and tell you try again without even a point penalty.
Not only correct, but also entered in the right syntax and form with correct derivative nuance for the slight possibility of Pearson's mymathlab to maybe not tell you to go fuck yourself.
Pearson's must have one hell of a contract with educators cause that shit hasn't improved at all in 20 years. One prof we had for multiple courses rallied against it. They eventually gave up and just carried over the grades to the gradebook. It's remarkable how quickly teaching in academia can knock a person down.
