convert/Legendre

convert special functions admitting 2F1 hypergeometric representation into Legendre functions

Calling Sequence

convert(expr, Legendre)

Parameters

expr

-

Maple expression, equation, or a set or list of them

Description

convert/Legendre converts, when possible, special functions admitting a 2F1 hypergeometric representation into Legendre functions. The Legendre functions are
