WebMay 16, 2024 · 2cosx is twice the cosine of angle x. It will be between −2 and 2. cos2x is an abbreviation for cos(2x). It is the cosine of the angle 2x, two times the angle x. The value of cos2x will be between −1 and 1. Before we think about double angles, let's remember the formula for the cosine of the sum of two angles: cos(a + b) = cosacosb −sinasinb.
