Abstract : Approximations are given for radial Mathieu functions of the first kind and second kind and for their derivatives. The results are essentially truncated series involving polynomials and the logarithm o parameters. The approximations are based on a knowledge of the usual expansions associated with the Mathieu functions (i. e., Fourier representations of the periodic functions, Bessel-functions series for the radial functions, etc.), and on the well-known series for the Bessel functions.
