Compute Tangent of an Angle in C

# Introduction

In this lab, you will learn how to compute the tangent of an angle in C programming. The lab covers the step-by-step process of reading an angle in radians, using the `tan()` function from the C math library to calculate the tangent value, and printing the result. By the end of this lab, you will have a solid understanding of performing trigonometric calculations in C.

The lab consists of two main steps: reading the angle in radians and using the `tan()` function to compute the tangent value. In the first step, you will learn how to prompt the user for an angle input in radians and store it in a variable. In the second step, you will apply the `tan()` function to the angle and display the resulting tangent value.
