<p>In <a href="page.php?w=calculus">calculus</a>, constants are treated in several different ways depending on the operation. For example, the <a href="page.php?w=derivative">derivative</a> (rate of change) of a constant function is zero. This is because constants, by definition, do not change. Their derivative is hence zero.</p>

<p>Conversely, when <a href="page.php?w=Antiderivative">integrating</a> a constant function, the constant is multiplied by</p><p>
