hello
we have been covering direct and inverse proportion at school. Are there any other types of proprtion?
We've been coming across questions like:
x is directly proportion to Y
Then I've been told to write
X (the proportion sign, which is like 8 on its side) Y
X=ky
We are then given a value for x and a value for y and asked to work out k. I'm fine with that but I'm wondering why we have to put "k"? Why does that proportion sign turn into "K"?
Also i was looking at the friedmann equation and i saw it had a "k" in it. When i see a physics equation like that will the K usually mean "constant" and will it have something to do with proportion?
thanks _Muddy_
