Question

i am taking calc and physics and all of a sudden h's started appearing in equations out of nowhere, what are they, and what do i do with them

Answer 1

Give an example and i would love to elaborate :)

Answer 2

Are you talkin about the h's in the equations of finding derivatives? but that's not really used in physics. So give an example and we'll help you out!

Answer 3

well we are using derivatives in physics but an example would be secant slope= deltaY over delta X or ((2+h)^(2)-2^(2))/h

Answer 4

in math in general the first letters of the alphabet are just constants. If you've noticed for variables math always uses x, y, z and even r, s, t, v etc. But when mathematicians want to symbolize a constant in an equation/formula they will use the first half of the alphabet. So pretty much in that secant slope formula, it's just meaning there will be a number you plug in there.

Answer 5

so it just the same as x basically?
okay makes sense i just never had a book throw in h
thank you
