# The Seen and The Unseen Part 4 Trigonometric Series

This is part 4 of the series The Seen and The Unseen. In part 4, I use the trigonometric series to explain how different decisions taken during implementation affect the seen and the unseen.

The trigonometric functions I will be working on are

# The Seen and The Unseen Part 3 Exponential Function

This is part 3 of The Seen and The Unseen Series. Part 2 covered how the seen and the unseen is affected by different implementation choices using geometric series. In part 3, I use the exponential function.

# The Seen and The Unseen Part 2 Geometric Series

This is part 2 of the series The Seen and The Unseen. In this part, I implement the geometric series and explain in detail how different decisions taken during implementation affect the seen and the unseen.

A simple geometric series expansion looks like this.

Programming is a skill anyone can learn with time and effort. I’ve been programming for four years and I am still learning. My general approach for learning any programming language was to understand the syntax and eventually develop expertise in this language by taking up problems and solving them in software. However, “proper” software development follows a procedure of gathering requirements and analyzing, designing, and developing implementations that meet those requirements. I started adding these steps to my practice. …
