An xyz-coordinate system is placed with its origin at the center of the earth, so that the equator is in the xy-plane, the North Pole has coordinates (0, 0, 3960), and the xz-plane contains the prime meridian. Find the coordinates (x, y, z) of Osaka, Japan, whose lotitude and longitude are 34.7 degrees north and 135.5 degrees east.

x = r cos(long)cos(lat)
y = r sin(long)cos(lat)
z = r sin(lat)
