Harmonic forms Harmonic forms comprise one useful subset of shapes. These include the following: t y(x,t) A Sin[27 + 4] -) t y(x,t) ACos[27 + ] T y(x,t)- A Exp[27i T t x y(x,t) A Exp[-2n i T where A is the wave amplitude, x is the spatial position, t is the time, lambda is the wavelength, Tis the wave period, and phi is an initial phase.
