I have a Silverlight user control that looks like a compass.I would post the image but i\'m a new user and can\'t post images yet. :(.
I wish to plot an ellipse by scanline finding the values for y for each value of x. For a plain ellipse the formula is trivial to find: y = Sqrt[b^2 - (b^2 x^2)/a^2]
for a 3d imaging software i am coding: I need to define an ellipsoid E, which can have any radii, centers and rotations in space
I 开发者_如何学Goneed to determine the X-radius & Y-radius of an ellipse give the major & minor radius and I couldn\'t find any way how to do it.
I need help adding an ellipsis to my pagination script. I can\'t find anything simple on Google. So that\'s why I ask on here. Thank you!!! Here is the code;
I would like to reproduce the following figure in MATLAB: There are two classes of points with X and Y coordinates. I\'d like to surround each class with an ellipse with one parameter of standard d
I have been trying from last three days and i was not able to solve this problem;ed the tables and query.
In a project I\'m working on the user creates a circle and choose a point on that circle, P=(px,py). For the question\'s sake, let\'s assume 开发者_JAVA百科the center of the circle is at (0,0).
I\'m struggling to figure out the math to convert between two different definitions of an arc. The source definition includes a start point, end point and control point on the arc as well as the ecce
I have to draw an ellipse of arbitrary size and orientation pixel by pixel.It seems pretty easy to draw an ellipse whose major and minor axes align with the x and y axes, but rotating the ellipse by a
