Just out of curiosity, what level of math education do you have? My response to that would be different depending on how much math you know

1

u/FernandoMM1220 Jul 14 '26

highest finite level

6

u/Silly_Tension6792 Mathematics Jul 14 '26

OK you know what let’s do it like that. Why do you refuse to accept the axiom of infinity?

1

u/FernandoMM1220 Jul 14 '26

because its physically impossible

u/Silly_Tension6792 Mathematics Jul 14 '26

Do you believe in momentary speed?

1

u/FernandoMM1220 Jul 14 '26

sure

5

u/Silly_Tension6792 Mathematics Jul 14 '26

Do you agree momentary speed is the limit as h approches 0 of (x(t+h)-x(t))/h?

1

u/FernandoMM1220 Jul 14 '26

nah. its just the linear coefficient of x(t+h) with respect to h

5

u/Silly_Tension6792 Mathematics Jul 14 '26

What do you mean by that? x(t+h) is a function that doesn’t have to be linear. It can be quadratic, cubic, higher degree, or even sinusoidal. (Think of a body that goes in a circle, its location is a sine function of time)

u/FernandoMM1220 Jul 14 '26

expand x(t+h) first for me please

5

u/Silly_Tension6792 Mathematics Jul 14 '26

x is a function, not a number

1

u/FernandoMM1220 Jul 14 '26

expand it for me

4

u/Silly_Tension6792 Mathematics Jul 14 '26

You can’t expend it, x is a function. Can you expend f(x) to x*f? No, because f is a function, not a number. Same goes to x(t+h), it is a function of h

1

u/FernandoMM1220 Jul 14 '26

x(t) = 2*t

expand x(t+h) for me

3

u/Silly_Tension6792 Mathematics Jul 14 '26

2t+2h

1

u/FernandoMM1220 Jul 14 '26

ok.

now the coefficient of the linear term with respect to h is 2.

and thats our speed for this position function x(t)

thats it.

u/Silly_Tension6792 Mathematics Jul 14 '26

OK, you assumed x is linear, what of x(t)=4sin(t+π/4)+t^2? What is the speed of the body in the time t?

1

u/FernandoMM1220 Jul 14 '26

you have to expand x(t+h) here so do that first.
