Trigonometry Expression API

📌 Overview

This API evaluates trigonometric expressions like sin(30) + cos(45) using mathjs and express.
It supports additional functions like log, ln, sqrt, and constants like pi and e.

🚀 Features

- Evaluate trigonometric functions: sin(), cos(), tan(), sec(), cosec(), cot()
- Support for mathematical operations: log(), ln(), sqrt()
- Constants available: pi, e
- REST API implementation with Express.js

🛠 Installation

```sh
const { trignometryExpression } = require("trigonometry-expression");
const { expression} = req.body;
const result = await trignometryExpression(expression);
