Description: In this "State of the Triangle" teaching address, President ObaMATH explores how to apply sum and difference identities with trigonometry. Trig sum and difference identities formulas help us evaluate sin, cos, tan, csc, sec, and cot of non special right triangle angles, like sin 15°, for example. Um, get ready to sing with us, seriously? Seriously. YAY MATH! Learning should always be fun and connective.
