take the sine of a number in javascript

To take the sine of a number in JavaScript, you can use the built-in Math.sin() function. Here's an example of how to use it:

index.tsx
const num = 0.5;
const sinNum = Math.sin(num);
console.log(sinNum); // output: 0.479425538604203
97 chars
4 lines

In this example, we're storing the number we want to find the sine of in a variable called num. We then apply the Math.sin() function to num and store the result in a new variable called sinNum. Finally, we use console.log() to print the value of sinNum to the console.

Note that the Math.sin() function uses radians, not degrees. If you have an angle in degrees that you want to find the sine of, you'll need to convert it to radians first. You can do this by multiplying the angle by Math.PI/180.
