Study Notes
Differentiation Overview
- Differentiation is a fundamental concept in calculus used to determine the rate at which a function changes.
- It is concerned with finding the derivative of a function.
Basic Concepts
- Derivative: The derivative of a function ( f(x) ) is denoted as ( f'(x) ) or ( \frac{df}{dx} ).
- Tangent Line: The derivative represents the slope of the tangent line to the curve at a given point.
Rules of Differentiation
- Power Rule: If ( f(x) = x^n ), then ( f'(x) = nx^{n-1} ).
- Constant Rule: If ( f(x) = c ) (constant), then ( f'(x) = 0 ).
- Sum Rule: If ( f(x) = g(x) + h(x) ), then ( f'(x) = g'(x) + h'(x) ).
- Difference Rule: If ( f(x) = g(x) - h(x) ), then ( f'(x) = g'(x) - h'(x) ).
- Product Rule: If ( f(x) = g(x) \cdot h(x) ), then ( f'(x) = g'(x)h(x) + g(x)h'(x) ).
- Quotient Rule: If ( f(x) = \frac{g(x)}{h(x)} ), then ( f'(x) = \frac{g'(x)h(x) - g(x)h'(x)}{[h(x)]^2} ).
Special Derivatives
- Exponential Functions: ( \frac{d}{dx}(e^x) = e^x )
- Logarithmic Functions: ( \frac{d}{dx}(\ln(x)) = \frac{1}{x} )
-
Trigonometric Functions:
- ( \frac{d}{dx}(\sin x) = \cos x )
- ( \frac{d}{dx}(\cos x) = -\sin x )
- ( \frac{d}{dx}(\tan x) = \sec^2 x )
Applications of Differentiation
- Finding the slope of a curve at a point.
- Identifying local maxima and minima (critical points).
- Analyzing the concavity of functions (second derivative test).
Higher Order Derivatives
- Second Derivative: Derivative of the derivative, used for analyzing acceleration and concavity.
- Denoted as ( f''(x) ) or ( \frac{d^2f}{dx^2} ).
Differentiation Techniques
- Implicit Differentiation: Used when dealing with equations where y is not explicitly solved for x.
- Logarithmic Differentiation: Useful for complex products and quotients.
Tips for Differentiation
- Always simplify the function if possible before differentiating.
- Remember to apply differentiation rules carefully based on the form of the function.
- Check for continuity and differentiability of the function first.
