stuff that seems rly hard one day might feel a lot more comfortable after 2 days working at it n sleeping to encode it all properly

(2/3)^x = A

(16/81)*A - A = (16/81)*A - (1)A

(16/81)*A - (1)A = (16/81 - 1) * A

Substitute (2/3)^x in for A

Yeah sleeping on a concept helps me way more than trying to hammer it into my brain when I’m exhausted.

Also generally speaking the more you struggle with a concept the higher chance you will acquire and really “get” it. So don’t view it like it’s some deficit on your part

im aware of the process of generating new synapses

i wonder how bad the diminishing return is though

this

another thing i wonder is if you spend all day trying to hammer math into your brain and then swap to an entirely new subject what happens

Hangover

there are subjects like pchem and linear algebra that are essentially the same thing, it's up to debate or preference whether you prefer learning two things at once or walking into a course having some background. While I don't like chemistry I do feel like physical chemistry teaches linear algebra pretty well, at least, taught me better than the linear algebra courses I took

factoring out image i completely understand intuitively

is that not a more difficult thing to factor? why do i understand that

youre just used to factoring single variables and their powers, and less used to factoring expressions involving numbers

anything ^x bothers me
to the point where I will just ln or log everything

on the upside im blazing through my homework now with everything i learned from studying for 28 hours of thelast 48

It seems you have strengths and weaknesses.
We all do.
You are better than me at some things.

the speed at which i do mental math about things i understand is of very high quality

in fact i challenge you to flash cards

I can calculate a 15% tip faster than anyone can pull up the calculator app on their phone.
Just something I am good at.

i just round up in my favor

Yeah I usually just do 20% myself.
Lots of friends who worked for tips.

i feel like my teacher used the worst videos on youtube for this

i have filled an entire notebook in 2 days
