WebReturns the arccosine, or inverse cosine, of a number. The arccosine is the angle whose cosine is number. The returned angle is given in radians in the range 0 (zero) to pi. Syntax. ACOS(number) The ACOS function syntax has the following arguments: Number Required. The cosine of the angle you want and must be from -1 to 1. WebThe period of the cosine function is 2π, therefore, the value of the function is equivalent every 2π units. For example, we know that we have cos (π) = 1. Every time we add 2π to the x values of the function, we have cos (π+2π). This is equivalent to cos (3π).
