What's important to note here is that the graph is a sinusoidal derivative of the maximum initial speed, which is denoted by v, a constant. Therefore the expression denoting the distance is merely a constant multiplied by sin2theta, a sine function with amplitude equal to the scaling constant (770sq/9.81), and period equal to 90 degrees (halved due to the coefficient of two)
