President Barack ObaMATH is back for an eye-opening lesson on graphing trigonometric functions! Specifically, we're graphing sin and cos, within one period, which is 2π. If you don't understand that now, you definitely will at the end of the video. That's because the Commander-in-TEACH uses the Unit Circle to calculate all the sin and cos values necessary, which is a great review for any algebra or calculus class. Great energy in the Oval Office today, YAY MATH!
