• There are three types of double-angle identity for cosine, and we use sum identity for cosine, first: cos (x + 21 Jul 2018 The posted expression is a trigonometric expression. The “cos” stands for the “ cosine” function, which is something you'll learn about in geometry or trigonometry ( It is written either cos -1 (x) or arccos(x). If you take the inverse cosine of both sides, you'll end up with: 2theta - pi/2 = cos -1 Click here to get an answer to your question ✍️ sin 5theta = cos 2theta, 0^o < theta < 120^o .
