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
Regular sound correspondences between Hungarian and other Uralic languages Regular sound correspondences between Hungarian and other Uralic languages There are numerous regular sound correspondences between Hungarian and the other Uralic languages. For example, Hungarian "á" corresponds to Khanty "o" in certain positions, and Hungarian "h" corresponds to Khanty "x", while Hungarian final "z" corresponds to Khanty final "t". These can be seen in Hungarian "ház" ("house") and Khanty "xot" ("house"), or Hungarian "száz" ("hundred") and Khanty "sot" ("hundred"). Hungarian and Khanty are closely connected, either genealogically or as part of a language area. The distance between Hungarian and the Finnic languages is greater, but the correspondences are also regular.
