Introduction to Derivatives
Derivatives are a fundamental concept in calculus that measure the rate of change of a function with respect to one of its variables.
Notation
- f'(x): The derivative of a function f at point x
- (dy/dx): The derivative of y with respect to x
- Δy/Δx: The average rate of change of y with respect to x
Rules of Differentiation
1. Power Rule
If f(x) = x^n, then f'(x) = nx^(n-1)
2. Product Rule
If f(x) = u(x)v(x), then f'(x) = u'(x)v(x) + u(x)v'(x)
3. Quotient Rule
If f(x) = u(x)/v(x), then f'(x) = (u'(x)v(x) - u(x)v'(x)) / v(x)^2
4. Chain Rule
If f(x) = g(h(x)), then f'(x) = g'(h(x)) * h'(x)
Geometric Interpretation
- The derivative of a function at a point represents the slope of the tangent line to the graph of the function at that point
- The derivative can be used to find the maximum and minimum values of a function
Higher-Order Derivatives
- The second derivative f''(x) represents the rate of change of the first derivative
- Higher-order derivatives can be used to analyze the curvature and concavity of a function
Applications of Derivatives
- Optimizing functions to find maximum and minimum values
- Determining the rate at which a quantity changes over time
- Analyzing the shape and behavior of functions
