Understanding Sine Function

The sine function is a fundamental trigonometric function that relates angles to the ratio of sides in a right triangle. For any angle θ, sin(θ) is defined as the ratio of the opposite side to the hypotenuse.

Key Properties of Sine

• Range: The sine function always outputs values between -1 and 1
• Period: Sine repeats every 360° or 2π radians
• Sin(0°) = 0
• Sin(90°) = 1
• Sin(180°) = 0
• Sin(270°) = -1

Common Applications

Sine functions are used extensively in:

• Wave physics and sound analysis
• Electrical engineering and signal processing
• Architecture and engineering calculations
• Computer graphics and animation
