Is F = Δp/Δt Equal to F = ma in This Algebra Question?

[JoshuaOB]

Hi all. Am I correct in that dt = Δt?
Thankyou!

Homework Statement

Show that F = \frac{Δp}{Δt} is equal to F = ma

Homework Equations

a = \frac{Δv}{Δt}
p = mΔv

The Attempt at a Solution

F = \frac{Δp}{Δt}
F = \frac{mΔv}{Δt}
F = ma

Δ usually means a finite difference. You can replace Δ with d in the limit where the difference goes to 0. In this case, I think they probably should have used d to begin with. So yes, I think that should be ok.

My apologies, they did use d to begin with. I typed it incorrectly.
