Dropping a pebble in a pond or striking the center of a large drum creates circular waves described by the zero-order Bessel Function, denoted, J0(r), where r is a normalized radial distance. At large normalized radial distances, the zero-order Bessel Function approaches the approximation:

1. 
2. Use Math class methods in a Java assignment statement that evaluates this large-distance approximation of J0(r).

Jo(r) square-root(2/(r)) * cosine(r-x/4)
