AcosBx

AcosBx refers to the mathematical function that computes the arccosine of the product of a constant 'A' and a variable 'x'. In essence, it is the inverse cosine function applied to the expression Ax. The arccosine function, denoted as arccos or cos⁻¹, returns the angle whose cosine is a given value. Therefore, AcosBx represents the angle whose cosine is Ax.

The domain of the standard arccosine function, arccos(y), is [-1, 1]. This means that the input to the arccosine function must be between -1 and 1, inclusive. Consequently, for AcosBx to be defined in the real number system, the value of Ax must fall within this range: -1 <= Ax <= 1. This inequality dictates the possible values of x for a given constant A. If A is not zero, then x must satisfy -1/|A| <= x <= 1/|A|.

The output of the arccosine function is an angle, typically measured in radians. The principal range of the arccosine function is [0, pi] radians, or [0, 180] degrees. Thus, AcosBx will yield an angle within this range. The function is continuous and monotonically decreasing over its defined domain. Its graph is a curve that starts at (1/A, 0) and decreases as x increases, reaching ( -1/A, pi).
