take the tangent of a number in typescript

To take the tangent of a number in TypeScript, you can use the built-in Math.tan() function. Here's an example code snippet:

index.ts
const x = 3; // the number we want to take the tangent of
const tangentResult = Math.tan(x); // calculate the tangent of x
console.log(tangentResult); // output: -0.1425465430742778

In this example, we first define the number we want to take the tangent of (in this case, x = 3). We then use the Math.tan() function to calculate the tangent of x, and store the result in a variable called tangentResult. Finally, we use the console.log() function to output the result to the console.

Note that the Math.tan() function expects its input to be in radians. If you have an angle in degrees, you can convert it to radians using the formula radians = degrees * (Math.PI / 180).
