Identify the period in degrees and radians:
y = sin2x:
y = cos(3/2)x:
y = 2sin(1/2)x:
y = 1.5cos0.25x:

  • Math -

    The period of a sine or cosine curve
    = 360°/k , where k is the coeffiecient of the angle

    e.g. your 1st question

    y = sin 2x , k = 2
    period = 360°/2
    = 180°

    or in radians:
    period = 2π/k = 2π/2 = π

    do the others the same way.
