So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!

Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.

* Off the top of my head *

1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it

    git remote add my-fork git@github...my-fork.git

Grab the brown and black knobs. You can also dial some of the numbers on the right.

Spherical coordinates are defined by ρ (rho, the distance from the origin), θ (theta, rotation parallel to the xy-plane), and φ (phi, inclination from the north pole to the south pole). This interactive drawing shows how they relate to the Cartesian xyz coordinates. The key is the horizontal slice of radius r.

• z = ρ cos φ
• r = ρ sin φ

Which makes sense: when φ=0, we're looking at the north pole, z=ρ and r=0. Then we're left with the familiar equations:

• x = r cos θ
