θ. A trigonometric identity that expresses the addition of one and cosine of double angle as the two times square of cosine of angle is called the one plus cosine double angle identity. 1 - cos²x = sin²x. this is important. just remember that . sin²x + cos²x = 1 then it follows from there :) Thanks for being part of this journey, I hope you will integrate well into my channel!
