# Parametric equation of rotated ellipse

**I used Mathematica to come up with the equation for an ellipse (and for a circle). Now I am looking for the parametric equation of parabola in space. My question: Would you write me the parametric equation for a parabola in 3-space, the same way as you wrote the equation for a 3D ellipse? Thanks for your help, Tamas **

Aug 28, 2012 · I need to draw rotated ellipse on a Gaussian distribution plot by surf. I am using a student version MATLAB. Can i still draw a ellipse center at estimated value without any toolbox that required money to buy.

Center-Orient Form. An ellipse in the standard form given by Equation (1) can be oriented via a rotation so that the major and minor axes are not necessarily parallel to the coordinate axes.

**However, when you graph the ellipse using the parametric equations, simply allow t to range from 0 to 2π radians to find the (x, y) coordinates for each value of t. Other forms of the equation Using the Pythagorean Theorem to find the points on the ellipse, we get the more common form of the equation. **

Standard parametric representation. Using trigonometric functions, a parametric representation of the standard ellipse + = is: (,) = (, ), ≤ < .The parameter t (called the eccentric anomaly in astronomy) is not the angle of ((), ()) with the x-axis, but has a geometric meaning due to Philippe de La Hire (see Drawing ellipses below). An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation.. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables.

Ellipses in parametric form are extremely similar to circles in parametric form except for the fact that ellipses do not have a radius. Therefore, we will use b to signify the radius along the y-axis and a to signify the radius along the x-axis. **Note that this is the same for both horizontal and vertical ellipses.
