### Topic: Tangent Space of Sphere

#### Kevin Shu (Jul 26 2020 at 17:36):

I want to do some calculus to minimize a function on a sphere. Using analysis/calculus/local_extr.lean, it seems like it should be possible if I can get the pos_tangent_cone_ata point on the sphere. Is there an easy way to get this?
