It’s all about the angles

Spent the day with some interesting trigonometry problems. Ended a very long day still with some interesting trigonometry problems. Gave the angles a wide birth in the end and now have a solution which uses line intersections and direction cosines using three dimensional cartesian coordinates. And I say my job is dull.

Walked Sasha, nice day. Went for a 15Km run. That was uneventful. Long day. Checking on weather. May give Ben a call, long time since last chopper session.
