The short answer is that Cos2x = (Cos x)2. Conversely, Cos(x)2 is equal to the Cosine of the squared value of x, a totally different value. To demonstrate, if the angle value (x) is equal to 30, the value of Cos2x will be: And the value of Cos(x)2 will be: Hope this ...

If you graph the cosine function for every possible angle, it forms a repeating up/down curve. This is known as a cosine wave. The curve begins at the maximum, (0, 1), because cos(0) = 1. As cosine approaches π/2, the value decreases to the x-axis. The value then continues to...
