Mathematics Quote by David Stipp
““The fact that trig functions cyclically output the same numbers as ever larger angles are plugged into them, by the way, explains why endlessly undulating "sinusoidal curves are produced when the sine and cosine functiins are graphed in the xy plane.””
About This Quote
Source Lecture: Mathematics or physics presentation, possibly a YouTube video
Trigonometric functions repeat their values periodically, creating sinusoidal patterns when graphed.
In simple terms: Trig functions repeat, making waves.
