Hello Friends Today, through this tutorial, I will tell you How to Write Program Cosine calculator using JavaScript with HTML. Sure, here’s a simple example of a cosine calculator using JavaScript with HTML:
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Cosine Calculator</title>
</head>
<body>
<h2>Cosine Calculator</h2>
<p>Enter an angle in degrees:</p>
<input type="number" id="angleInput" placeholder="Angle in degrees">
<button onclick="calculateCosine()">Calculate</button>
<p id="result"></p>
<script>
function calculateCosine() {
// Get the input value
var angleDegrees = document.getElementById("angleInput").value;
// Convert degrees to radians
var angleRadians = angleDegrees * Math.PI / 180;
// Calculate the cosine
var cosineValue = Math.cos(angleRadians);
// Display the result
document.getElementById("result").innerHTML = "Cosine of " + angleDegrees + " degrees is " + cosineValue.toFixed(4);
}
</script>
</body>
</html>
This code creates a simple webpage with an input field for the angle in degrees and a button to calculate the cosine of that angle. When the button is clicked, it triggers the `calculateCosine()` function, which retrieves the input value, converts it to radians, calculates the cosine using `Math.cos()`, and then displays the result on the page.
Example:-

Enter an angle in degrees:
