Unlock the Power of Trigonometry in C++: Mastering the tan() Function
Trigonometry is an essential aspect of mathematics, and C++ provides a range of functions to work with trigonometric calculations. One such function is tan(), which calculates the tangent of an angle. But how does it work, and what are its parameters?
Understanding the tan() Function
The tan() function is defined in the <cmath> header file and has been a part of the C++ standard since C++ 11. It takes a single mandatory argument, which is the angle in radians. This angle can be positive, negative, or zero.
The Return Value: Understanding the Range
The tan() function returns a value within the range of [-∞, ∞]. This means that the output can be any real number, from negative infinity to positive infinity.
Practical Applications: Examples to Get You Started
Let’s dive into some examples to illustrate how the tan() function works in C++.
Example 1: Basic tan() Functionality
When you run the program, the output will be:
tan(3.14159 / 4) = 0.999051
Example 2: Working with Integral Types
When you run the program, the output will be:
tan(45) = 1
