Approximate an Integral Using the Trapezoidal Rule in C

# Introduction

In this lab, we will learn how to approximate an integral using the trapezoidal rule in C. The lab covers the following steps: 1) defining the function f(x) and the interval [a, b], 2) splitting the interval and applying the trapezoidal formula to calculate the approximate integral, and 3) printing the final result. This lab aims to provide a practical understanding of numerical integration techniques using the C programming language.
