<p>answer only if you're sure</p>
<p>does sin^2(x) = sin (x^2)? or = (sinx)^2</p>
<p>what about log^2(x). is there even such a thing? if so, is there any difference when taking the derivative of a log as opposed to taking the derivative of a trig function?</p>
<p>sin^2(x) = (sinx)^2</p>
<p>i've never seen a log^2(x). i'm pretty sure this notation only applies to trig functions.</p>
<p>Yeah, sin^2(x) is the same thing as (sin x)^2.</p>
<p>I'm pretty sure there's no such thing as log^2(x). I've never seen it, at least. It's simply expressed as (log x)^2.</p>
<p>mm, as to your last question...yea o.O, of course they're different, right? Could you rephrase your question?</p>
