The path of a bullet is parabolic. You ain't hitting shit with that math, yo.

At that range, using a linear estimation is fine I assure you

Both linear linear and parabolic descriptions of a bullet trajectory are approximations of a drag curve, that can be obtained only numerically.

On short distance you do

That's just what they want you to think

Define x motherfucker

[-] Haagel@lemmings.world 9 points 6 months ago

Serious question: is x = my + b also a slope intercept? Why is it only calculated via the y axis?

[-] SandbagTiara2816@lemmy.dbzer0.com 16 points 6 months ago

It’s convention, I think. If I remember correctly, you always put y on the left, because you can also write equations as functions of a variable, x, with the symbology f(x) = mx + b. That way you can integrate and derive the function easily, since m and b are constants, and all your x variables are on one side.

If I were to encounter x = my + b, the first thing I would do, just by nature at this point, would be to convert it to y = (x - b) / m.

It’s been a while since I took math, and I was never the best, so others should feel free to correct me.

Correct. Y is a response to X. How does y change as x changes? If I need to achieve this y, what does my x need to be? By convention, y is the dependent variable and x is the independent variable, m is slope, and a, b, c are constants.

....... I may have 3am brain, but the intercept is y=b....

Slope intercept formula???

That's a formula for a line, y intercept is x=0...

Shit is affine, yo

Pull the trig-ger

[-] AnnaFrankfurter@lemmy.ml 1 points 6 months ago

Or you can take it's derivative at that point

[-] FilthyShrooms@lemmy.world 1 points 6 months ago

Ok, but what's the quadratic formula?
