Differential Calculus Differential calculus revolves around the concept of the derivative which represents the instantaneous rate of change of a function Its essentially the slope of the tangent line to the function at a specific point The derivative of a function fx is denoted by fx or dfdx Key Concepts Limits Limits are fundamental to differential calculus They describe the behavior of a function as its input approaches a particular value Limits are essential for defining continuity and derivatives Continuity A function is continuous at a point if its graph can be drawn without lifting the pen Continuity is a prerequisite for differentiability meaning a function must be continuous at a point to be differentiable at that point Derivatives The derivative measures the instantaneous rate of change of a function It tells us how much the output of a function changes in response to a small change in its input Common Differentiation Rules Power Rule ddx xn nxn1 Product
