how do u state the period of a function?
for ex.
f(x)=sin((1/2)x)

  • Pre-Calculus -

    for y = sin kx, the period is 2pi/k radians or 360/k º

    so your period is 360/1/2) = 720º

    BTW, the same rule applies to the cosine function, but for the tangent function the period is pi/k radians or 180/kº
