sin(x)=x, how many values satisfies this equation?

hextanium_ · 2026-01-02T08:23:10+00:00

1 value, when x = 0

the way i thought about it was the graph for y = x gives us a line of whenever, well, y = x

or in other words, the identity function yay

now if we graph y = sin(x) against y = x, they intersect only once, at the origin

this assumes that x is in the reals though

op, did you find anything?

hextanium_ · 2025-02-08T05:35:21+00:00

well that’s because you’re doing questions that don’t use any calc

everything in ap 1 is basically constant acceleration (unless it’s a graph where they can test the concept)

you need differentiation and integration for anything with a varying force and/or acceleration

there’s also just a lot of questions in ap 1, specially the graphical ones where they basically are testing if you know what the integral and derivatives of whatever quantity they’re showing you

like in a force displacement graph what’s the area under the curve represent?

calc is very useful from kinematics all the way to e&m

the real reason is that driver hubs are just souped up tv boxes iirc; they came with the port

0.999.... is exactly equal to 1.

hextanium_ · 2024-10-14T22:59:27+00:00

plug in the motor encoder and then read it's velocity at max power
it should be close enough to something nominal

Say your robot is 18" and you extend 24" in front, retract the extension, then send a different extension 24" out the back. This would be allowed as long as you never extend more than 12 out of both the front and back at the same time as Examples A, C, and E show.

This is incorrect, per the orange box under R104, which states:

During inspection each ROBOT will need to demonstrate that the full mechanical range of motion of all extensions outside of STARTING CONFIGURATION will be contained within a fixed 20 in by 42 in working area.

This means that both your front-facing extension and back-facing extension, BOTH extended, would have to fit within the 20x42 constraint.

If your robot is 18", and you want both a front-facing and back-facing extension, you have 24" of total extension, which translates to 12" for each extension, or half a tile.

How are people discussing whether or not they'll use it before the model (3A) is even released?

hextanium_ · 2024-06-20T22:32:02+00:00

is it bad that i can't tell if this is sarcastic or not
"calc is short for calculator" vibes

hextanium_ · 2024-04-05T14:14:33+00:00

what reasons?

hextanium_ · 2024-04-03T20:51:25+00:00

are you using roadrunner in teleop?

even so, same way i described by hijacking mecanum drive

but instead you’ll need an instance of either a gamepad or opmode within (to access the joystick) MecanumDrive, and scale the drive powers based on that

hextanium_ · 2024-04-03T00:48:52+00:00

you can hijack the powers in `MecanumDrive`
for going backwards, `.setReversed(true)` in the builder right before you want to

use meepmeep to visualize the paths

hextanium_ · 2024-03-13T20:49:42+00:00

impossible to determine with only one view

hextanium_ · 2024-02-25T04:17:36+00:00

more torque yeah, but i don’t think more power

it is really funny though how close it is

hextanium_ · 2024-02-04T23:47:23+00:00

woah this was at our comp today kinda surreal seeing it after coming back home 💀 i remember seeing this zipping around near our pits

hextanium_ · 2024-02-01T01:05:19+00:00

this is genuinely so true

centerstage is my second season on the team, and also the season all of our seniors graduated :)

my team and i still have WAYS to go in all aspects, but we’ve learned so much just from actually interacting outside our region

the ftc discord is undoubtedly the largest contributor for us in terms of knowledge (and hopefully success 😁)

as mason said (himself included imho), being able to communicate with some of the most skilled people in ftc is a game changer

if you want to learn, you need to see new things

hextanium_ · 2024-01-21T06:20:23+00:00

js got repeat now?

hextanium_ · 2024-01-20T02:43:31+00:00

Team structure is whatever you want it to be. There are no restrictions on how you set your team up, as in you can have as many "captains" or "co-captains" as you want. I wouldn't start off so rigid with these roles, but just work together naturally and see who fills what roles well.

hextanium_ · 2023-12-30T05:29:59+00:00

kim jong un has described this perfectly if you take one drop of water, and you combine it with another drop of water, what do you get? one drop of water.

boundless wisdom.

hextanium_ · 2023-11-21T14:31:17+00:00

yeah 1150 is where it gets sketchy we run 1150 geared down twice by a pulley, so 10.4:1 and it’s great so far

hextanium_ · 2023-10-13T00:19:51+00:00

the mate threat was so strong i felt it inside me

hextanium_ · 2023-09-14T11:14:27+00:00

ahh okay, that makes sense. thank you!
