Trigonometric Identities, part 1 of 2
In his last days in the "Elliptical Office," the Commander-in-TEACH, President ObaMATH, immortalizes his math skills on video, specifically, teaching us about trigonometric identities. We first review the major trigonometric functions, then get down to business by covering the Pythagorean Identities. We'll work to make sure you're learning and conceptualizing trig identities, instead of always having to memorize them. May God Bless the United Math of America, and YAY MATH!
