    Simplifying intersection point of lines with parameters

    I'm kind of lost on simplifying this formula: \frac{u+\lambda*\cos(\epsilon + \alpha)}{\cos(\epsilon)}- \frac{v+\lambda*\sin(\epsilon + \alpha)}{\sin(\epsilon)}= 0 I'm no math-student, just trying to play around with interference patterns, anyways... I try to figure out what \lambda is...

    Formula for this point distrubution on a sphere?

    sphere A series of points are plotted on a unit radius sphere with its center at the origin of the coordinate system, see image. Points on XY and XZ planes (marked yellow) are created so that horizontal points coordinates in spherical system (r,fi,theta) are (1, n*A, 0) and vertical are (1, 0...

    How can I make lines of equal lengths to all directions from a central point?

    I made a problem in my mind that I can't seem to solve. I need an answer because it is quite fundamental to me, because it is about the expansion of things like the universe. This is the problem; I can't understand how to make lines of equal lengths to all directions from a central point. I...

    Equation for a _________ curve perpendicular to a line at a given point on the line

    Hi, I'm not sure whether calculus is the right thing for this, but I believe it is. I only have a loose memory of it from high school - 10 years ago, but I am nearly certain this is possible. Practically, my project starts with the idea of a triangle, and the idea is to bow out (or pinch in)...
