DefinitionMultivariable calculus, refers to the branch of calculus where function of two or more variables are studied. This covers the methods for differentiation, integrations and optimisation of multi-variable functions. In much the way that single-variable calculus helps us understand one-dimensional motion (if we know the position of an object at all times, then we can determine everything else about its motion)multivariable calculus helps us to analyze the two-dimensional motion. I.e., At the naked minimum, this allows us to study surfaces, volumes, and rates of change across many dimensions!! “Yes, the idea of the gradient vector, divergence and curl are all from multivariable calculus and are methods of describing how a vector field behaves in three dimensions.”
