If the object were rotating clockwise (negative angle), then the equations of TIME would read. x = 3 cos (-t), y = 2 sin (-t) And now as time moves forward, the object rotates clockwise (negative angle). This example can be a bit confusing because the parameter could be angle.

WebNov 16, 2024 · For the ellipse and the circle we’ve given two parameterizations, one tracing out the curve clockwise and the other counter-clockwise. As we’ll eventually see the direction that the curve is traced out can, on occasion, change the answer. Also, both of these “start” on the positive x -axis at t = 0. Now let’s move on to line integrals. WebFeb 27, 2024 · Example 1.2.1. Here are three different parametrizations of the semi-circle x2 + y2 = r2, y ≥ 0. The first uses the polar angle θ as the parameter. We have already seen, in Example 1.0.1, the parametrization. The second uses x as the parameter. Just solving x2 + y2 = r2, y ≥ 0 for y as a function of x, gives y(x) = √r2 − x2 and so ...

WebSummary. A function with a one-dimensional input and a multidimensional output can be thought of as drawing a curve in space. Such a function is called a parametric function, and its input is called a parameter. Sometimes in multivariable calculus, you need to find a parametric function that draws a particular curve.
