Cnoidal wave is the wave height, "λ" is the wavelength, "c" is the phase speed and "η" is the trough elevation. Further cn is one of the Jacobi elliptic functions and "K"("m") is the complete elliptic integral of the first kind; both are dependent on the elliptic parameter "m". The latter, "m", determines the shape of the cnoidal wave. For "m" equal to zero the cnoidal wave becomes a cosine function, while for values close to one the cnoidal wave gets peaked crests and (very) flat troughs. For values of "m" less than 0.95, the cnoidal function can be approximated with trigonometric
The Crests & The Crests", producing a single for United Artists in 1962, two singles for Cameo Records in 1963-64, a single for APT Records in 1965, a single for Scepter Records in 1965, and three singles for the Parkway label in 1966. James Ancrum then took over the lead, recording "Guilty" in January 1962 and charting only to #123. The group went back to touring when their 1963 Selma side "Did I Remember?" flopped. A 1964 sequel to "16 Candles", "You Blew Out The Candles", also was not successful. In 1965, J.T. Carter and Mel Tillison signed with Decca Records and
