· Graphs: Each function has a unique wave-like graph that repeats itself. · Special Angles: Some angles have easy-to-remember sin, cos, and tan values, like 30, 45, and 60 degrees. · Formulas: There are tons of formulas for adding angles, doubling angles, and even cutting angles in...
In summary, we defined, tested and practiced using double angle formulas. A double angle formula defines the relationship between trigonometric functions and the double of an angle. We first looked at the formula for sine, which is sin(2x) = 2sin(x) cos(x). Then we looked at cosine, wh...
