    y = Asin(θ) = Asin(wt-2πx/lambda), where w = 2πf and lambda = v/f.

    Thus in terms of the given values, y = Asin(2πft-2πfx/v) = Asin(2πf(t-x/v))

    Note that use of the sine function is an arbitrary choice. It could just as well be the cosine.

    EDIT: hello? Don't forget the sin or cos, or you'll have an unlimited y.

    Find the wavelength, lambda, first from v and f. Then equation is y = Amplitude (2Pi"x"/lambda - 2Pifrequency"t")
