Syntax

math.sin(angle)
  • angle: The angle in radians.

Example

In this example, math.sin() calculates the sine of a 90 degree angle (π/2 radians).

local angle = math.pi / 2
local answer = math.sin(angle)


local output = string.format("The sine of %.4f is approximately %.0f", angle, answer)
print(output)

This is the resulting output:

The sine of 1.5708 is approximately 1
