<p>In <a href="page.php?w=mathematics">mathematics</a>, the <b>derivative</b> is a fundamental tool that quantifies the sensitivity to change of a <a href="page.php?w=Function_%28mathematics%29">function</a>'s output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is the <a href="page.php?w=slope">slope</a> of the <a href="page.php?w=Tangent">tangent line</a> to the <a href="page.php?w=graph_of_a_function">graph of the function</a> at that point. The tangent line is the best <a href="page.php?w=linear_approximation">linear approximation</a></p><p>
