Summing the digits of 2024 yields:
2+0+2+4=8
Rotating 8 by 90˚ yields the infinity symbol
What is Gojo's Technique?
INFINITY
What does this mean?
Gojo is coming back in 2024

stop gatekeeping plz

if you can get rid of intellectual property/copyright as a concept within society i will

Quick question just for my general knowledge - How many of ya'll are tutored or used to do tutoring for during senior years?

Majority of the people in my cohort take tutoring (although many deny it) and I think it's the main reason they excel. Although I haven't done tutoring for any senior subjects, I was wondering how many people here, do tutoring and whether it helps...

Bonus Q - Do you tell your peers/friends/teachers about taking tutoring or 'hide' it?

i did online tutoring for a while but i don't think it really helped, i wish i could do some in person tutoring (idk i think it works better than online tutoring) and yeah i told my friends that i did online tutoring, i don't understand why some people try to hide it tho

Why can't you do in person?

just questioning if i can skip the $\frac{du}{dx} = -5 \,\rightarrow\, dx = -\frac{du}5$ and just say $u = 1-5x \,\rightarrow\, dx = -\frac{du}5$ bcz i'm too ceebs to write it all out
$\begin{align*} \int\,&\frac{1}{\left(1-5x\right)^3}\,dx\\ \text{Let } u&=1-5x\\ \frac{du}{dx}&=-5\\ \implies dx&=-\frac{du}{5}\\ \int\,\frac{1}{\left(1-5x\right)^3}\,dx&=-\int\,u^{-3}\,\frac{du}{5}\\ &=-\frac{1}{5}\int u^{-3}\,du\\ &=-\frac{1}{5}\left(\frac{u^{-2}}{2}\right) + C\\ &=-\left(-\frac{u^{-2}}{10}\right)+C\\ &=\frac{1}{10\left(1-5x\right)^2}+C \end{align*}$

na
u could write it like:
x=-u/5
\therefore dx=-du/5

alternatively u can skip like 8 of those lines if u consider 1-5x as x

as average boreduser said (kinda), your working is hella unnecessary
u can rewrite it as like

$\begin{align*} \int \frac{1}{(1-5x)^3} \text dx &=\int (1-5x)^{-3} \text dx \\ &= \(1-5x)^{-2} \cdot \frac{1}{-2} \cdot \frac{1}{-5} + C \\ &= \frac{1}{10(1-5x)^2} + C \end{align*}$

uh the qn asked for substitution (sorry should've clarified)

the plan is to import the average mark from each individual sheet to the 'Analytics' sheet –> colour indicator if your average is meeting your goals or not as well as the other pages but this requires making custom scripts
this is most definitely not a good use of my time but it's fine it's motivation woops the reds are mismatched i hate selecting in colour palettes

woah this is so cool can you make like a blank copy and share it with eveyrone when you're done?? this seems super useful
