Sin 135 degrees.

Explanation: For sin 0 degrees, the angle 0° lies on the positive x-axis. Thus, sin 0° value = 0. Since the sine function is a periodic function, we can represent sin 0° as, sin 0 degrees = sin (0° + n × 360°), n ∈ Z. ⇒ sin 0° = sin 360° = sin 720°, and so on. Note: Since, sine is an odd function, the value of sin (-0°) = -sin (0 ...Degrees. Degrees are a unit of measurement for angles, representing the rotation between two rays. The degree angle system divides a full rotation into 360 units called degrees. In mathematics, the degree symbol is used to represent an angle measured in degrees. The symbol is also used in physics to represent the unit of temperature: Fahrenheit.From your diagram, rotating 135 degrees anti-clockwise results in thumb up (and +ve value for sin(135)).
