Tangent Line:

A tangent line is a straight line that touches a curve at only one point. It represents the instantaneous rate of change or slope of the curve at that specific point.

Differential Equation:

A differential equation relates an unknown function with its derivatives. It describes how a function changes based on its current state and can be used to model various phenomena in science and engineering.

Linear Approximation: Linear approximation is an estimation technique that uses tangent lines to approximate values of functions near a given point. It provides a close approximation when dealing with small changes or intervals.
