MHB Sketch Parametric Curve and Find Cartesian Equation

Click For Summary
The discussion focuses on sketching the parametric curve defined by the equations x = cos(θ) and y = sec(θ) for 0 ≤ θ < π/2. The key point is that the parameter can be eliminated to derive the Cartesian equation, resulting in y = 1/x. Participants express a mix of confusion and realization regarding the elimination process. The conversation highlights the importance of understanding the relationship between parametric and Cartesian forms. Ultimately, the participant acknowledges their oversight in recognizing the already completed elimination of the parameter.

sketch the parametric curve and eliminate the parameter to find the cartesian equation of the curve $x=\cos\left({\theta}\right)$, $y=\sec\left({\theta}\right)$, $0\le \theta < \pi/2$

$y=\frac{1}{\cos\left({\theta}\right)}=\frac{1}{x}$

i sketched the curve. how do i do the second part?

You've already eliminated the parameter when you wrote:

$$y=\frac{1}{\cos(\theta)}=\frac{1}{x}$$
 
oh. wow I am really stupid. hahaha thanks (Tongueout)
 
Thread 'Problem with calculating projections of curl using rotation of contour'
Hello! I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem. Given: ##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0## ##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1## ##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0## I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
