At Desmos, we imagine a world of universal math literacy . 15. Log InorSign Up. Calculus: Integral with adjustable bounds. The sine and cosine functions have the property that f ( x + P) = f ( x) for a certain P. This means that the function values repeat for every P units on the x -axis. The Desmos Graphing Calculator considers any equation or inequality written in terms of r r and to be in polar form and will plot it as a polar curve or region. Statistical Functions. The absolute value of the constant A (amplitude) increases the total range and the constant D (vertical shift) shifts the graph vertically. Examples.
