A crucial fact is always that one can differentiate (locate a derivative) on the differentiable manifold, and this allows us to notice down any challenge with intervening differential equations (like Newton’s gravitation principle or Einstein’s relativity theory). Which is why we phone it «differentiable». It can be certainly unachievable to https://fellowfavorite.com/story20529781/new-step-by-step-map-for-bos138
