**[SOLVED] Latitude Longitude -> Polar Form -> Cartesian Coordinates**

## Homework Statement

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).

## Homework Equations

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

## 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??
