- CSS trigonometric functions, particularly `sin()` and `cos()`, were voted the 'Most Hated Feature' in the State of CSS 2025 survey.
- Despite the negative perception, trigonometric functions in CSS are powerful for creating circular and wavy layouts without relying on magic numbers.
- The `sin()` and `cos()` functions map angles to Cartesian coordinates, enabling precise placement of elements around a circle or along a wave.
- Practical applications include circular menus, DNA-like intertwined chains, and damped oscillatory animations for dynamic UI effects.
- The article introduces the concept of damped oscillation, demonstrating how to model it in CSS for animations that gradually come to rest.
- Future articles will explore other trigonometric functions like `tan()` and inverse functions (`asin()`, `acos()`, `atan()`, `atan2()`), expanding on their uses in CSS.
