Personal Growth - Theodore Teddy Bear Schiele

This is the message to my developer:

To create a web form for your website that allows clients to input their personal data and calculate their potential growth based on your “Wealth Navigator Formula”, you’ll need an HTML form with input fields corresponding to each variable in the formulas you’ve provided. Below is an HTML example that includes JavaScript for simple calculations directly on the client’s browser:

htmlCopy code<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Wealth Navigator Formula</title>
<script>
function calculateWealth() {
    var P = parseFloat(document.getElementById('initialInvestment').value);
    var r = parseFloat(document.getElementById('annualReturn').value);
    var n = parseFloat(document.getElementById('investmentYears').value);
    var G = P * Math.pow((1 + r), n);
    document.getElementById('result').innerHTML = "Future Wealth: $" + G.toFixed(2);
    
    var Ri = parseFloat(document.getElementById('returnOutcomes').value);
    var Pi = parseFloat(document.getElementById('probabilityOutcomes').value);
    var ER = Ri * Pi;
    document.getElementById('expectedReturn').innerHTML = "Expected Return: $" + ER.toFixed(2);
    
    var k = parseInt(document.getElementById('successfulInvestments').value);
    var binomialResult = binomial(n, k, Pi);
    document.getElementById('binomialProbability').innerHTML = "Probability of Success: " + binomialResult.toFixed(4);
}

function binomial(n, k, p) {
    var coeff = factorial(n) / (factorial(k) * factorial(n - k));
    return coeff * Math.pow(p, k) * Math.pow((1 - p), (n - k));
}

function factorial(x) {
    if (x === 0) {
        return 1;
    }
    return x * factorial(x - 1);
}
</script>
</head>

    <button type="submit">Calculate</button>
</form>

<p id="result"></p>
<p id="expectedReturn"></p>
<p id="binomialProbability"></p>
</body>
</html>

This HTML document creates a simple user interface with input fields for the initial investment, annual return rate, number of years, return outcomes, probability of outcomes, and the number of successful investments needed. When the user inputs these values and submits the form, the JavaScript functions calculate the future wealth, expected return, and the probability of achieving the defined number of successful investments using the binomial probability model. The results are then displayed on the page without the need to reload.

This basic example can be enhanced with more sophisticated error handling, styling, and functionality according to your needs and the specific calculations required by your formula.
