<h2>The Math.sin() Method</h2>
<p>Math.sin() returns the sine of an angel given in radians.</p>
<p>To use degrees, convert the degrees to radians first:</p>

<script>
document.getElementById("demo").innerHTML =
"The sine of 0 degrees is: " + sine(0) +
"<br>" +
"The sine of 30 degrees is: " + sine(30) +
"<br>" +
"The sine of 90 degrees is: " + sine(90) +
"<br>" +
"The sine of 150 degrees is: " + sine(150) +
"<br>" +
"The sine of 180 degrees is: " + sine(180) +
"<br>" +
"The sine of 210 degrees is: " + sine(210) +
"<br>" +
"The sine of 270 degrees is: " + sine(270) +
"<br>" +
"The sine of 360 degrees is: " + sine(360);
function sine(degree) {
let x = Math.sin(degree * Math.PI / 180);
return x.toFixed(2);
