Differential geometry is a branch of mathematics that uses the techniques of calculus and linear algebra to study the properties of geometric objects, particularly those that are curved, such as surfaces and manifolds. It combines concepts from both differential calculus, which deals with the notion of smoothness and rates of change, and geometry, concerning the properties and relations of points, lines, surfaces, and solids.
