f(x) = sqrt(25 - x^2); find the derivative in javascript

To find the derivative of the function f(x) = √(25 - x^2) using JavaScript, you can use the built-in Math.sqrt and Math.pow functions. Here's the code to calculate the derivative:

index.tsx
function derivative(x) {
  return (-x) / Math.sqrt(25 - Math.pow(x, 2));
}

// Example usage
var x = 4;
var result = derivative(x);
console.log(result);

In this code, we define a function derivative that takes a value x as input and returns the derivative of the function at that point. We use the power operator Math.pow to calculate x^2 and Math.sqrt to calculate the square root. We then apply the derivative formula for the function f(x) = √(25 - x^2), which is (-x) / √(25 - x^2).

You can test the code by passing different values of x to the derivative function. The result will be printed to the console.
