A periodic function is a function for which a specific horizontal shift, P, results in the original function: f ( x + P ) = f ( x ) for all values of x. When this occurs we call the smallest such horizontal shift with P > 0 the period of the function.

24 lip 2021 · When you study pre-calculus, you are crossing the bridge from algebra II to Calculus. Pre-calculus involves graphing, dealing with angles and geometric shapes such as circles and triangles, and finding absolute values.
We can have all of them in one equation: y = A sin(B(x + C)) + D. amplitude is A; period is 2 π /B; phase shift is C (positive is to the left) vertical shift is D; And here is how it looks on a graph: Note that we are using radians here, not degrees, and there are 2 π radians in a full rotation.
