Final answer:
A multivariable derivative calculator computes the derivatives, enabling the calculation of rates of change in functions that have more than one variable.
Step-by-step explanation:
A multivariable derivative calculator computes derivatives of functions with more than one variable. In calculus, a derivative represents the rate at which one quantity changes with respect to another. When we talk about the derivative of a velocity function with respect to time, we are discussing the gradient of a velocity-time graph, which physically interprets the acceleration. Conversely, when we calculate an integral, we are often finding areas, such as the area under a velocity-time graph, which represents displacement. The limits are used to define the derivative, while exponents could appear as part of the expression being differentiated.
