Eliminate the parameter from the given pair of trigonometric equations where \(0t2\pi\) and sketch the graph. I can solve many problems, but has it's limitations as expected. about conic sections, is pretty clear. Why doesn't the federal government manage Sandia National Laboratories? Eliminate the parameter for each of the plane curves described by the following parametric equations and describe the resulting graph. $$0 \le \le $$. of t, how can we relate them? definitely not the same thing. So let's pick t is equal to 0. t is equal to pi over 2. So that's our x-axis. When we are given a set of parametric equations and need to find an equivalent Cartesian equation, we are essentially eliminating the parameter. However, there are various methods we can use to rewrite a set of parametric equations as a Cartesian equation. The parameter t that is added to determine the pair or set that is used to calculate the various shapes in the parametric equations calculator must be eliminated or removed when converting these equations to a normal one. Now let's do the y's. And so what is x when The domain for the parametric equation \(y=\log(t)\) is restricted to \(t>0\); we limit the domain on \(y=\log{(x2)}^2\) to \(x>2\). It's frequently the case that you do not end up with #y# as a function of #x# when eliminating the parameter from a set of parametric equations. x = t2, y = t3 (a) Sketch the curve by using the parametric equations to plot points. Why? The parametric equations restrict the domain on $x=\sqrt(t)+2$ to $t \geq 0$; we restrict the domain on x to $x \geq 2$. Eliminate the parameter t to rewrite the parametric equation as a Cartesian equation. \[\begin{align*} {\cos}^2 t+{\sin}^2 t &= 1 \\ {\left(\dfrac{x}{4}\right)}^2+{\left(\dfrac{y}{3}\right)}^2 &=1 \\ \dfrac{x^2}{16}+\dfrac{y^2}{9} &=1 \end{align*}\]. If the domain becomes restricted in the set of parametric equations, and the function does not allow the same values for \(x\) as the domain of the rectangular equation, then the graphs will be different. Example 10.6.6: Eliminating the Parameter in Logarithmic Equations Eliminate the parameter and write as a Cartesian equation: x(t)=t+2 and y . The graph of the parametric equation is shown in Figure \(\PageIndex{8a}\). See Example \(\PageIndex{9}\). To make sure that the parametric equations are the same as the Cartesian equation, check the domains. Eliminate the parameter to find a Cartesian equation of the curve.
