Calculate the area of the spherical triangle defined by the points (0, 0, 1), (0, 1, 0) and (1/√2, 0, 1/√2)
From the spherical Gauss-Bonnet Formula, where T is a triangle with interior angles α, β, γ. Then the area of the triangle T is α+β+γ-π.
How do I work out the interior angles in order to use this formula?
Any help appreciated.
