Circular functions have several standard features. The function has a <em>midline</em> that is the line for which half the points on the curve lie above the line and half the points on the curve lie below. A circular function's <em>amplitude</em> is the maximum deviation of the function value from the midline; the amplitude corresponds to the radius of the circle that generates the function. Circular functions also repeat themselves, and we call the smallest value of <m>p</m> for which <m>f(x+p) = f(x)</m> for all <m>x</m> the period of the function. The period of a circular function corresponds to the circumference of the circle that generates the function.
