<p>Imagine how <strong><em>ed I was when I found out that small angle </em></strong>** was just the equation for the period of a pendulum…</p>
<p>It should make you feel better though that if you put that you probably wouldn’t get any points without work.</p>
<p>So I did the small angle approximation wrong and maybe even incorrect calculus, but I got the same answer T = 2 pi / sqrt(mgx/I). I said sin = 1 instead of sin = theta and then square rooted both sides, moved the variables over and integrated both sides then put 2pi in for theta and solved for the time variable which I said was the period. I wonder how many points I would get? ;p</p>
<p>could someone post their answer to FRQ#1 on Mechanics.
thanks.
i just want to see if my answer was close.</p>
