take the cosecant of a number in typescript

To find the cosecant of a number in typescript, we can use the 1/Math.sin() function. Cosecant is the reciprocal of sine, so we can calculate it by taking the reciprocal of the sine function's return value for the given number. Here's an example:

index.ts
let num = 45; // angle in degrees
let cosecant = 1/Math.sin(num * Math.PI/180);
console.log(cosecant); // output: 1.4142

In the above example, we converted the angle from degrees to radians using the formula num * Math.PI/180, and then found the sine of that angle using the Math.sin() function. Finally, we took the reciprocal of the sine to find the cosecant of the given angle.
