<p>how do you find arctan(4) by hand???</p>
<p>arctan(4)=theta</p>
<p>tan (theta)=4...</p>
<p>actually i'm not sure how u'd do that by hand...</p>
<p>No that's wrong cujoe. F+ for the year. Tsk.</p>
<p>haha... i don't know, i've been out of trig too long... was it 8th or 9th grade... <em>sigh</em> sophomores</p>
<p>it should be an angle measure, anybody??</p>
<p>lol I was actually joking..maybe it was right? ;)</p>
<p>I'm not sure but my teacher told us to do: 1/ [tan(4)]</p>
