 <p>Once I have the amplitude and period, it’s time to write a formula to calculate the circle’s x-position as a function of time (the current frame count):</p>

 let x = amplitude * sin(TWO_PI * frameCount / period);</pre>
-<p>Think about what’s going here. First, whatever value the <code>sin()</code> function returns is multiplied by <code>amplitude</code>. As you saw in Figure 3.10, the output of the sine function oscillates between –1 and 1. Multiplying that value by my chosen amplitude—call it <em>a</em>—gives me the desired result: a value that oscillates between –<em>a</em> and <em>a</em>. (This is also a place where you could use p5.js’s <code>map()</code> function to map the output of <code>sin()</code> to a custom range.)</p>

 <p>Now, think about what’s inside the <code>sin()</code> function:</p>
 <pre class="codesplit" data-code-language="javascript">TWO_PI * frameCount / period</pre>
 <p>What’s going on here? Start with what you know. I’ve explained that sine has a period of <span data-type="equation">2\pi</span>, meaning it will start at 0 and repeat at <span data-type="equation">2\pi</span>, <span data-type="equation">4\pi</span>, <span data-type="equation">6\pi</span>, and so on. If my desired period of oscillation is 120 frames, I want the circle to be in the same position when <code>frameCount</code> is at 120 frames, 240 frames, 360 frames, and so on. Here, <code>frameCount</code> is the only value changing over time; it starts at 0 and counts upward. Let’s take a look at what the formula yields as <code>frameCount</code> increases.</p>
