Move along an Arc

Here's some pseudocode I made for going to a point in an arc.

``` python
for t in [30, 45, 60, 90]: #More angles?
 rz = sin(to.z > from.z ? -t : t) * (to.z - from.z)
 rx = cos(to.x > from.x ? -t : t) * (to.x - from.x)
 ry = tan(to.y < from.y ? -t : t) * (to.y - from.y)
 move(rx, ry, rz)
```

Thoughts @VoltzLive?
