    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...

    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=...
