Web5 years ago. A sinusoidal function is one with a smooth, repetitive oscillation. "Sinusoidal" comes from "sine", because the sine function is a smooth, repetitive oscillation. Examples of everyday things which can be represented by sinusoidal functions are a swinging pendulum, a bouncing spring, or a vibrating guitar string.

How to Graph Sine and Cosine Functions: 15 Steps (with Pictures) - wikiHow

WebA graphing calculator can be used to graph functions, solve equations, identify function properties, and perform tasks with variables. What role do online graphing calculators play? Graphing calculators are an important tool for math students beginning of first year algebra. It helps with concepts such as graphing functions, polynomials ... WebGraphing Sine and Cosine Functions Recall that the sine and cosine functions relate real number values to the x - and y -coordinates of a point on the unit circle. So what do they look like on a graph on a coordinate plane? Let’s start with the sine function. We can create a table of values and use them to sketch a graph. WebTo calculate the midline -- x = 0 if not shifted horizontally, y = d. For cos graphs do this: To calculate the extremum point -- x = 0 if not shifted horizontally , a+d. To calculate the midline -- 1/4 period or 2pi/b, y = d. … dx code for contact with sharp object
