    Graduate Equation (with polar coordinates) of circle on a sphere

    i have tried many way (intersection plane A x + B y + C z = D with sphere x^2 + y^2 + z^2 = R^2, intersect cylinder (or cone) with sphere) but I'm searching the simpliest algebrically solution ... PS soultion with programs like Wolframalpha or Derive for...

    Graduate Equation (with polar coordinates) of circle on a sphere

    hi, i'm a newbie... i have this problem: i have a sphere with known and constant R (obvious), i have two point with spherical coordinates P1=(R,p_1,t_1) and P0=(R, p_0, t_0) p_x = phi x = latitude x t_x = theta x =longitude x the distance between point is D=...
