Formulas for Trigonometric Functions: Sum/Difference, Double/Half-Angle, Prod-to-Sum/Sum-to-Prod
9分29秒
説明
There are tons of formulas we can learn that involve trigonometric functions. These help us evaluate trig functions for angles that are half of a common angle, twice a common angle, the sum or difference of two common angles, all kinds of stuff. They are a little annoying to learn but they are super useful so let's just bite the bullet and knock them all out in one clip!
