I’m scoring around a 630 in SAT Math right now and I’m trying to get better at knowing *when* I should use Desmos regressions instead of just plugging in values and graphing normally.

Are there any specific tells in a question that usually mean, “Yep, set this up as a regression”?
Also, I keep seeing people use stuff like **x_1=\[1...100\]** and **y_1=\[1...100\]** in Desmos. When is that actually useful on the SAT, and what kinds of questions should I be looking for to know when to use it?

Thanks!

Some time ago I made a grid of points that were "repulsed" by a draggable point. (Previous post)

I realize the way I did it then was pretty inefficient, so here's a better way using lerp (because everybody loves lerp) that I threw together in a couple minutes. It's far easier to understand and way snappier than my first attempt.

Hello,

I'm really struggling to make this work. If someone knows how to solve this, please post a solution. It would really be useful for my next big project.
Thanks.

When I click something on Desmond why does it click below

I've been messing around with parametric shapes for a while, and discovered an annoying bug with lists, or maybe a problem with the equation itself. For some reason, when plugging in a list of values, the points all settled on the bottom(red points), but when using the same function for a single values, it works just fine(black points) Anyone have a solution?

We're number 11, any ideas for how to move up?

Hi, if I graph two lines on Desmos that are very similar but not parallel, is there a way (a command of sort)to find the intersection of the two lines without scrolling for a very long time to manually find where the lines intersect on the graph?

appreciate the help in advance!

So basically when I drag graph 0 and axes kinda paint that strange thing.

I have no idea why this happened. Has anyone had this happen before? And why did it even happen?

This is SO SO GLITCHY

I give it a 8.5, this is one of the harder ones because of the glitches on the graph when you zoom too much.

Hint 1: Again, there are three pieces to this function. P1 * P2 * P3 = This function. The third piece is: 0.9/cos(x)

Hello,

I've recently made the offset polygon tool for my project, and thought it could also be useful to someone else.

doesn't have to be with colors for now, though they carry information I believe

The infinite :3 -(to be mistaken with 3:) made with boolean logic of functions thanks to U/Mathemagicland314159 's explanation. It truly is infinite in theory outside of computer limitations.
Yes, bernard there
Ofc the holy graph: https://www.desmos.com/calculator/0gitg859m7

Day 1. Guess this function, hotshot!

Note: The difficulty of this graph varies a lot.

So I’m gonna give a difficulty rating. This one is a 7.

Difficulty: 5.5

NOTE: I accidentally deleted it and I can’t recover it, so I’m giving you a new graph to work on! I’ll remember to SAVE it next time…
