The fundamental theorem of calculus is used not only for curves, but for surfaces and they also look as though they are needed in [[green’s_theorem]], [[stokes’_theorem]], and [[the_divergence_theorem]]. Isaac Newton (and Leibniz) discovered differentiation, and [all of calculus is based on this]. %%visits: 2 # diary - :journal: # intuition The link between an integral and the gradient of it. # rigour ∫C∇f⋅ = f(q) − f(p) for curve integrals # examples
