As someone who had to take remedial algebra classes I can answer this
It's because a lot of people don't go to college immediately after high school, and you forgot how to do a lot of math when you never use it.
So unironically the smartass kids who say "but when will we ever use this in the real world?" are right for most people.

Most majors require passing at least college algebra. So Tiffany in Early Childhood Education and Dakshuan in African Diaspora Studies are forced to take a class that's far more advanced than anything they had to bother with in high school. It might take them several tries to pass but since it's required and is the only math class they must take, the number of failures for College Algebra increases quickly. The next easiest and next most difficult math classes have less failures because less students take them and they're not core classes.

For unrelated reasons, I've had the opportunity to work through at least 10 different US college level calculus books and they were all piss easy in the sense that there never was any tricks or challenging problems where you had to be creative. For the most part it was incredibly straightforward. The only notable exception is one book that had section with challenging and Putnam problems. My own analysis classes were essentially based on interesting and tricky problems. I've never seen a problem where you had to split an integral into an infinite series of integrals, sum the series then solve that to obtain the solution. It's always TEE HEE WE JUST SAID \int 1/x dx = ln|x|, HERE'S 50 PROBLEMS THAT NEED u SUBSTITUTION.

No, these
$<br />\cos x = \frac{1}{2}(e^{ix} + e^{-ix}), \enspace \sin x = \frac{1}{2i}(e^{ix} - e^{-ix})<br />$
etc.. makes it trivial to modify or derive a bunch of trig ids when you need them.

For 3x3 anty-symmetric matrices, that's

pic related. More broadly

$\sum_{k=0}^\infty a_k J^k = a_0\,E + \sum_{i=0}^\infty \left(a_{2i+1}\, E + a_{2i+2}\, J\right)\,(j^{2})^iJ$

but if you don't go with z^k/k! then the connection to the trig identity is entirely lost as far as recognizability goes.

Im taking a management course and they want us to study Maslows hierarchy of needs.

Clearly this shit is incredibly oversimplified to a point where its retarded and useless.
Maslow himself even admitted that and this thing has been revised multiple times but every textbook insists on teaching the most outdated form.
I took a behavioural science course prior to this so I understand motivation on a more meaningful level compared to this crap.

Here's the thing, what am I supposed to do here? Do I go for the debate and explain to my teacher how this works, who probably doesnt care/know anyway?

I dont understand why we have to learn this.
I know psychology students get upset over having to learn about Freud, but at least he was correct on some things

Waste of taxpayer money, Florida is doing just fine getting everyone sick. The CIA chemical weapon attacks should be directed at places with high vaccination rates to pick off as many of the still-vulnerable as possible; those areas will need way more help.

literally, the protests have been quite minor, and people have gone along with close to absolutely ridiculous requests, and have not actually had to deal with much or any covid at all around them. I might have had it I'm not sure. A coworker did have it but was surprised at the positive result, it was just a cold to him.

you just can't blame antivaxxers, when my whole state basically shut down in preparation for getting ass blasted, and still has not had to deal with many deaths. So far my county has 230 cases out of 115k people or .002%

and lots of people are getting vaccinated. so what more is there? butt stuff? do we need to put the vaccine in our butts? these variants are just another tease. this is starting to feel like the wait for climate change or jesus coming back

i was barely affected by all the social shit so far and even I am like just filled with this stressful waiting
