Trigonometric functions play an important role in computer graphics and animation. However, using them can be tricky. Here are some reasons why:

• Complexity: The math involved can get really complicated, making programming tough.
• Precision: Even tiny mistakes in these functions can create visual problems.
• Performance: Making images in real-time needs fast and efficient methods, which can be hard to improve.

To solve these problems, developers usually use special libraries. These libraries package these functions, making them easier to use and helping everything run better.
