<p>Probably a stupid question but anyways:</p>

<p>My textbook reads that the diffEQ for rate of change of a population in logistic growth is :</p>

<p>ky(1 - y/L)</p>

<p>where L is the carrying capacity and k is the constant.</p>

<p>My review book says (petersons, very good one, latest edition) that the same equation is</p>

<p>ky(L - y)</p>

<p>where L is the carrying capacity and k is the constant.</p>

<p>We just had an exam, and i used my review books equation for this and he marked my work wrong .....</p>

<p>Is the review book wrong? Or are these equations the same thing somehow?</p>
