TWO EXPANSIONS SUITABLE FOR COMPUTING THE ZEROS OF LEGENDRE FUNCTIONS

Wang Bingzhong (Institute of Applied Physics)  
Using the appropriate series expansion for the Legendre functions valid for θ≈π,the zeros of P_(vn)~1 (cosθ)and d/dθP_(μn)~1(cosθ)are computed numerically.For θ=165°, the results computed here are in good agreement with those given by Ref.[1~2]. The first seventeenth zeros are also given in this paper forθ=175°, 177° and 179°.
