The Commander-in-TEACH debuts with our first lesson from the Oval Office! (Or perhaps, an amazing Oval Office studio set.) Here, President ObaMATH waxes poetic on the Law of Sines for Trigonometry. A simpler rule than the Law of Cosines, this law involves trigonometric ratios, in order to solve any triangle. However, what isn't always so simple is the Ambiguous Case, which we cover here, using a unique method NOT done in the books. Great interaction by the POTUS's student cabinet members. YAY MATH!
