Questions tagged [parametric-equations]

A parametric equation is a mathematical definition of a set of values defined by a function of one or several parameters. They are frequently used for defining curves by using a parametrized function defining the coordinates of the curve's points.

How to draw frequency separation in a parametric equalizer

I'm trying to do something similar to this parametric equalizer, in regards to the frequency axis only, i.e. the values along the middle line: This appears to be the standard format for equalizers but I can't work out the formula to do this. i.e.…

Plotting a Parametric Curve in MatLab with a Double

I am trying to plot the parametric equation (t, -4, t^2 + 17), but am running into difficulties. I have been trying fplot3(t, -4, t.^2+17) But am getting the following error: Undefined function 'fplot3' for input arguments of type 'double'. Any…

How do I plot a function with different values of various parameters on gnuplot?

I want to plot this parametric funtion x(t)=a+(n/w)*(cos(w*t)-1)-((g/w**2)*sin(l)-m/w)*(sin(w*t)+(g*t/w)*sin(l)) y(t)=b+((g/w**2)*sin(l)-m/w)*(cos(w*t)-1)+(n/w)*sin(w*t) But I have various parameters a,b,m,n,w,k,g y I want to vary a,b,m,n,w,k…

Bounding Ellipse Implementation in Java

I'm scratching my head with the implementation of an algorithm I have been led to believe will calculate the coefficients to an equation that will give me an ellipse that will bound a set of points. Given that I don't know how the algorithm actually…

Random line segments using parametric equations

I am trying to crate a program that randomly generates line segments using parametric equations. What I have created kinds of does the job, but instead of the lines being disconnected from one another they form one continues line. This is what I…

Parametric equations for sphere surface tangent plane

Excuse my first post, it is literally that. I've been banging my head for three days trying to get squares to align properly on a sphere. Does anyone know the parametric equations for the tangents of a plane? See tangents X, Y and Z in the code…

Parametric Circles Scrolling + Arrays

I've been working on this problem for a while now, but can't seem to find a way around it. I am trying to build a horizontal scroll wheel module (made up of "layers" array) with a "selector" layer in the middle of the screen that selects the layer…

Creating parametric equations using points

I have points, x, y, and t, where t=1,...,Length[x]. I wished to make two parametric equation using the idea of interpolation, but not using the method in Mathematica. Any suggestion?

Equalizing lines approximating bezier curve

I have a cubic Bézier curve defined by f(t) where t is in the interval [0..1], and I have approximated the Bézier curve with an n + 1 vertex polyline represented in an array called p, each vertex being p[i] for i in 0..n, where p[i] = f(i /…

rotating a vector using parametric equation of 3d circle

I'm not getting the required output i.e x2,y2,z2 in below code. Here the angle t is in degree, (x2,y2,z2) is the pint of vector face after being rotated and (a2,b2,c2) is the direction cosine of the rotated vector.I used rviz to visualize the…

Solveing for the change in the parameter of a set of parametric equations

I'm trying to write a bit of code that will calculate the values of X and Y as Q changes. I think I need to do this based on parametric equations because I need to plot vertical lines as well as other curves to find acceleration and velocity at…

Deconstruct Bezier Curve into Line Segments with Equally Spaced Slopes

I'm currently working on a program that takes a scale SVG file of a race track and uses the data to approximate the track as an array of points. Ideally, the absolute value of the slopes between any two consecutive points would be identical, as this…

Why B-Spline are defined only where basis function sum to 1?

I'm trying to understand b-spline. It's not clear why << The curve is defined only where order basis functions overlap>>, where order is degree+1 (for a cubic the order is 4). I found also that where a number equal to the order of basis functions…
