<p>can someone show me how to solve this limit problem?</p>
<p>LIM as X goes to
positive infinity:</p>
<h2>([sq. rt. of x+1] - [sq. rt. of x-1])X</h2>
<pre><code> (sq. rt. of Xsquared + 1)
</code></pre>
<p>any replies would be much appreciated..thanks</p>
<p>I'm not sure but could you plug it into your graphing calculator and evaluate it graphically?</p>
<p>0? it seems that the top is getting smaller as the bottom is getting bigger</p>
<p>Let a = the entire expression without the limit.</p>
<p>Then lim n->infinity (a) = lim n->inf (sqrt(a squared)) = sqrt (lim n->inf(a squared)). You should be able to do it from there with a little simplification.</p>
<p>nvm i think its 1</p>
