What is rate of change? I don't understand it. What does it mean that a curve has a rate of change at a certain point? Please explain like I'm retarded, because I obviously am.

I think I'm scratching the surface of it tho, say a formula f(x)=sth gives me a y value for a certain x, depending on the formula, as I increase/move about with my x's, 1,2,3,4,5,6 etc. I get different y values at those x points clearly, but those y values will rarely be in a "sequence" as the aforementioned x values, so instead of getting f(x)'s 2,4,6,8,10, I might be getting something as 4, 8, 16, 400, 1000, trillion, so would the rate of change in what I'm trying to convey be a description of how fast there is a change to y values dependent on me plugging in consecutive x (1,2,3,4...) values?

Like, I don't even know what I just said. I'm tackling calculus, and yeah. Can't wrap my head around it all. Also, how does an instantaneous rate of change even make sense? (please use whatever else but speed as an example, since I can understand when it's about speed but not when it's about anything else)

To find the distance of a point from origin, would you really just do
[math]
\sqrt{x^2 + y^2}
[/math]
?

>> No.9411914

>>9411907
No. I'd check which coordinate is the biggest, and do this (assuming it's x):
[eqn]\left|x\right|\, \sqrt{1 \,+\, \left(\frac yx\right)^2 \,+\, \left(\frac zx\right)^2}[/eqn]
That prevents the float value overflowing to infinity.

>> No.9411925

>>9411882
if you have a linear function f(x) = ax + b, it's reasonable to think that its "rate of change" is the same at all points, and is equal to the "a" coefficient - the function grows slower with smaller "a". the rate of change of an arbitrary function is then looking at the function like "if it was a linear function" and taking the "a" coefficient. this is precisely the derivative

>> No.9411958

>>9411882
If you move along a curve, what rate is the y-value increasing/decreasing at? If it is a flat line, the rate of change is zero. If it is a diagonal line, it is increasing at some rate. For instance, a function y=5x+3 is increasing at a rate of 5. For a parabola like y=2x^2+4x+1, the rate of change is 4x+4 (which was found by taking the derivative).

Now, you can also apply this to the rate of change of x, or the rate of change of any variable. So for example, if we put the linear equation from earlier in terms of x we get x=y/5-3/5, and if we derive this we get the rate of change of x, which is 1/5.

You should watch a youtube video on it. Try patrickjmt.

Thanks bro

>> No.9411977

>>9411958
Basically, the derivative at a certain point of interest is, for this much x I will get this much y, at this particular point. Or so. I think I fianlyl get it.

>> No.9412000

>>9411977
Yup! You can also have negative rates of change, like if you have y=-5x+3 the line is decreasing at a rate of five along the curve. So in that case its "for this much x, i will lose this much y"

That very question has been confusing evolutionary quantum physicists for millennia. The currently accepted theory is that traps aren't two dimensional, but rather have a hidden third dimension which allows them to store cum without having testicles.
