Understanding Trigonometric Functions
Sine (sin): The sine function represents the ratio of the opposite side to the hypotenuse in a right triangle. It's periodic with a period of 2π radians (360°) and ranges from -1 to 1.
Cosine (cos): The cosine function represents the ratio of the adjacent side to the hypotenuse in a right triangle. Like sine, it's periodic with a period of 2π radians and ranges from -1 to 1.
Tangent (tan): The tangent function is the ratio of the opposite side to the adjacent side, or equivalently, sin/cos. It has a period of π radians (180°) and can take any real value.
Inverse Functions: Arcsin, arccos, and arctan are inverse trigonometric functions that help you find angles when you know the trigonometric ratio. They're essential for solving triangles and analyzing periodic phenomena.
