I think so, there isn't much else that can explain the classroom scene where half the class are all playing the same goofy animation at 5 frames per second, mostly in sync. It would have looked better to have them not moving at all, so at least some of the jank was a stylistic choice on gamefreak's part.
Your numbers are all over the place and don't really make sense for what you're talking about. 3 plus two groups of 6 would only be 15 out of 20, so where did the other 5 people go?
But more to the point, if those 3 stop pedaling, or pedal harder than everyone else combined, or apply the brakes, or tip the bike over, any number of other things they could absolutely change the speed/direction of the bike.
Polar Functions and dydx
We are interested in the lines tangent a given graph, regardless of whether that graph is produced by rectangular, parametric, or polar equations. In each of these contexts, the slope of the tangent line is dydx. Given r=f(θ), we are generally not concerned with r′=f′(θ); that describes how fast r changes with respect to θ. Instead, we will use x=f(θ)cosθ, y=f(θ)sinθ to compute dydx.
From the link above. I really don't understand why you seem to think a tangent line in polar coordinates would be a circle.
A straight line in polar coordinates with the same tangent would be a circle.
I'm not sure that's true. In non-euclidean geometry it might be, but aren't polar coordinates just an alternative way of expressing cartesian?
Looking at a libre textbook, it seems to be showing that a tangent line in polar coordinates is still a straight line, not a circle.
food pyramid
You're really showing your age with this one. The food pyramid got replaced 13 years ago
You could at least make it easy and post a link to the pdf
Looking at the Food & Drink section, it doesn't look like you can get much more than coffee and meat with monero, so I'm really not sure how you're supposed to "be your own bank" by using it and still have access to food.
Have you heard of D&D Beyond? It's already a subscription service, I'm not sure D&D is in the best hands as it is.
I only used it to replay Kingdom Hearts a few years ago, but I never had any issues with it. And based on this video RPCS3 released yesterday, it looks like there are plenty of games that are very playable, by any definition.
I do not. The previous study of its kind from the IMO was from 2014 and looked at the years 2007-2012, so it seems to take a few years for them to be able to put all the information together.
I don't know how long that video actually is, but a lot of it is made up of unrelated clips of lions and tigers not even in the same location with a couple of clips of lions and tigers "fighting" for less than a minute before they both back off.
