Title: constant of proportionality
Post by: #1procrastinator on October 06, 2011, 03:00:25 pm

If a is proportional to b and also proportional to c, why does it make sense to multiply b and c and work from there to find the k?

I also notice if you find the constants individually, and combine them, you get a^2 - why?

Could you provide an example question?

If you mean for the second part, nevermind about that! (I worked it out...actually, there was no problem at all, i simply didn't notice that it's the just constant times the proportion will give you the number and when you coming a bunch of them, it's just the same number multiplied by itself)

But for the first part...well, I can't think of anything else really..find the constant of proportionality if a is proportional to b and c?
