<title>Calculus Review</title>
<!-- Optional introduction -->
<introduction>
<p>
In Calculus I, you learned about derivatives, antiderivatives, and definite integrals.
All of these will make an appearance in the context of probability density functions, cumulative distribution functions, and probability calculations in continuous sample spaces, so it will be useful to refresh your memory and practice some calculations.

<title>Fundamental Theorem of Calculus</title>
<statement>
<p>
If <m>F(x)</m> is an antiderivative of <m>f(x)</m><mdash />i.e., if <m>F'(x) = f(x)</m><mdash />then:
<md>
<mrow> \int_a^b f(x)\ dx = F(x)\bigg|_a^b = F(b) - F(a). </mrow>
</md>
</p>
</statement>
</theorem>
<p>
If <m>f(x)</m> is a probability density function (don't worry about what that means for now), then integrals such as <m>\int_a^b f(x)\ dx</m> are used to calculate certain probabilities, as are values of the form <m>F(x)</m>.
