The answer is divorce.
someone asked for our house wifi pw. It is a math thing and they were a math person (high school math teacher) that didnāt know what I was talking about. I was disappointed in them, but they were still impressed and learned something new. My DGS and SiL learned something new during their recent visit too 
Me too. I live in statistics every day but Calc is not part of any routine in my life. My brain hurts a bit even trying to refresh reading through an integral. I did see the answer when searching though 
Iāve not posted those kinds of problems for a reason
I donāt think this will give you a pin code. That might be the biggest joke.
It should give an actual value. I might even be able to remember how to do that one.
Without looking, or doing anything to remember anythingā¦I came up with 16 (or, more properly, 0016)?
No idea if that is actually correct.
This is no longer a fun thred.
Not all jokes are funny.
It doesnāt.
The problem set is stupid, though, because you can literally type the integral into a kidās calculator and it will give you the answer.
Iāve been slowly dusting off my brain for a lot of the more advanced math as my kids progressed. Been a looong time since Iāve worked with integrals - but looks like my daughter is going into something with the humanities so I may not have to break that back out.
It is nice that my daughter thinks I can remember some techniques on the fly even though I hadnāt thought about them in 40 years. But, Iāve done pretty well if she gives me a little time to stare at things. 
Anyway, I cheated with Wolfram Alpha.
Even the internet was likeā¦ eff that noise.
Respect.
How did you get to sec(x) = Ā½ (t+1/t) ? Thatās the tricky part, I think.
Clearly Iām wrong. But I realized why. I was stupid in that I never actually took the integral of anything! I just plugged in the lower and upper limits, etc. See. I clearly need a refresher.
Along that lines, Iāve toyed with going back to get my Masterās degree. But one of the fears I have is that any of those classes might require me to actually recall that Calculus that I obviously canāt remember how to do!
Ok you just made me realize how old I actually am and I donāt like that one bit. However, I went back to grad school 11 years after I finished to add a concentration to my degree and it was so much harder to do than I imagined. I was always pretty decent in school and made good grades fairly easily, but omg that was tough bc so many skills had atrophied, as well as new technologies introduced in that time.
