Unlock the Power of Trigonometry: Mastering the atan() Function
Understanding the Basics
The atan() function, defined in the <cmath> header file, is a fundamental component of trigonometry in C++. As of the C++ 11 standard, this function has been refined to provide accurate results. But what exactly does it do?
Unraveling the Mystery
The atan() function takes a single mandatory argument, which can be positive, negative, or zero. This flexibility makes it a valuable tool for various mathematical applications. So, what’s the return value of this function?
The Return Value Revealed
The atan() function returns a value within the range of [-π/2, π/2]. This bounded range ensures that the output is always within a predictable and manageable scope.
Putting atan() into Action
Let’s explore two examples to demonstrate how atan() works its magic.
Example 1: A Simple Demonstration
When you run the program, the output will reveal the power of atan() in calculating the arctangent of a given value.
Example 2: Working with Integral Types
In this example, we’ll see how atan() handles integral types with ease. The output will showcase the function’s versatility and accuracy.
