sin θ = 0 when θ = 0 , 180, 360.
Maximum value of sin θ is 1 when θ = 90 . Minimum value of sin θ is –1 when θ = 270 . So, the range of values of sin θ is –1 ≤ sin θ ≤ 1.
As the point θ moves round the unit circle in either the clockwise or anticlockwise direction, the sine curve above repeats itself for every interval of 360. The interval over which the sine wave repeats itself is called the period
