Trigonometry Just Got Shocking—Watch What Happens When You Derivative a Sine Wave Trigonometry is far more than just memorizing identities and unit circle values. For students and enthusiasts alike, the moment calculus meets the sine wave is a revelation—one that’s both shocking and utterly fascinating. If you’ve ever wondered how calculus illuminates the behavior of periodic functions, now’s your chance to witness it firsthand. ### The Shocking Derivative of Sine: A Deep Dive At first glance, the sine function, \\( y = \\sin(x) \\), seems smooth and rhythmic—a gentle oscillation between -1 and 1. But dive a little deeper with calculus, and the real magic unfolds: the derivative of \\( \\sin(x) \\) is \\( \\cos(x) \\).
