(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Latitude Longitude -> Polar Form -> Cartesian Coordinates

1. The problem statement, all variables and given/known data

I need to convert 46 Degrees North 80 Degrees west into Cartesian coordinates, based on the assumption that the earth is a sphere (althought it's not).

2. Relevant equations

http://en.wikipedia.org/wiki/Spherical_coordinate_system

3. The attempt at a solution

I've attempted to convert and I got ( -767.18, -4350.91, 4575 )

Not sure if this is correct. I'd like to know the North and West signs factor into the equation when plugging in. Can anyone help, or show me a step by step basis please??
