For math, science, nutrition, history. F ( x) = 2sin ( x )cos ( x) kevin further explains that he's read the textbook and knows the product rule states that if you have a function f ( x) = u * v, where u and v are both continuous. The final solution is all the values that make sin(x)(1+2cos(x)) = 0 sin ( x) ( 1 + 2 cos ( x)) = 0 true. So that sin2x = 2 sin x cos x.
