Key Concepts

Derivative

The derivative of a function is the instantaneous rate of change or the slope of the tangent line at any given point. It forms the basis for the concept of differentials, as the derivative determines how much the function will change for a small increment dx, thereby allowing for approximations of ?y.

Chain Rule

The chain rule is critical in computing the derivative of composite functions. When a function comprises an inner and an outer function, the chain rule helps differentiate by multiplying the derivative of the outer function by the derivative of the inner function, ensuring that the combined rate of change is accurately calculated.

Differentials

Differentials provide a method to approximate changes in a function's value. Specifically, if y = f(x) and there is a small change dx in x, then the differential dy = f?'(x) dx approximates the resulting change in y. This is particularly useful in estimating small variations near a known point of the function.

Linear Approximation

Linear approximation, or tangent line approximation, uses the fact that differentiable functions are nearly linear in a small neighborhood around a point. By using the derivative at that point, one can estimate the function's value after a small change, making it easier to calculate approximate increments in function values.
