(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Show that this equation is dimensionally correct.

y = (2m)cos(kx), where k = 2m^-1

2. Relevant equations

None that I know of.

3. The attempt at a solution

I don't know why this is correct. I have looked through the chapter and all of the dimensional analysis examples(there are only three) list what the variables represent. The only information given is what I have typed, so I am just assuming that m represents meters.

Are trig. functions dimensionless?
