29 Δεκ 2020 · The set of all points (x, y) = (f(t), g(t)) in the Cartesian plane, as t varies over I, is the graph of the parametric equations x = f(t) and y = g(t), where t is the parameter. A curve is a graph along with the parametric equations that define it. This is a formal definition of the word curve.
After studying this chapter you should. be familiar with cartesian and parametric equations of a curve; be able to sketch simple curves; be able to recognise the rectangular hyperbola; be able to use the general equation of a circle; be able to differentiate simple functions when expressed parametrically.
10 Νοε 2020 · Plot a curve described by parametric equations. Convert the parametric equations of a curve into the form y = f(x). Recognize the parametric equations of basic curves, such as a line and a circle. Recognize the parametric equations of a cycloid. In this section we examine parametric equations and their graphs.
5 Ιουλ 2023 · In this section we will introduce parametric equations and parametric curves (i.e. graphs of parametric equations). We will graph several sets of parametric equations and discuss how to eliminate the parameter to get an algebraic equation which will often help with the graphing process.
