this is just a general trig question:(adsbygoogle = window.adsbygoogle || []).push({});

We are going over Malus law in physics; the formula is this:

S = s*cos^2(theta)

My question is about the cosine squared term in the equation. does this simply mean take the cosine of a number and square it? in other words would this be the same thing as [cos(theta)]^2
