Study Notes
Introduction to Calculus
- Calculus is a branch of mathematics focused on change, encompassing differential and integral calculus.
- Differential calculus examines rates of change, curve slopes, and tangents.
- Integral calculus deals with accumulation, areas under curves, and volumes of solids.
Differentiation
- Differentiation finds the derivative, the instantaneous rate of change of a function at a point.
- The derivative shows the slope of the tangent line to the function's graph at that point.
- The derivative of function f(x) is denoted as f'(x) or dy/dx.
Basic Differentiation Rules
- Constant Rule: The derivative of a constant is zero. d/dx(c) = 0 (c is a constant)
- Power Rule: The derivative of xn is nxn-1. d/dx(xn) = nxn-1
- Constant Multiple Rule: The derivative of a constant times a function is the constant times the function's derivative. d/dx(cf(x)) = c * d/dx(f(x))
- Sum/Difference Rule: The derivative of a sum or difference of functions is the sum or difference of their derivatives. d/dx(f(x) ± g(x)) = f'(x) ± g'(x)
- Product Rule: The derivative of a product of two functions is the first function times the derivative of the second, plus the second function times the derivative of the first. d/dx(f(x) * g(x)) = f(x) * g'(x) + g(x) * f'(x)
- Quotient Rule: The derivative of a quotient is the denominator times the numerator's derivative minus the numerator times the denominator's derivative, all divided by the denominator squared. d/dx(f(x) / g(x)) = [g(x) * f'(x) - f(x) * g'(x)] / [g(x)]2
Derivatives of Common Functions
- Derivative of sin(x): cos(x)
- Derivative of cos(x): -sin(x)
- Derivative of ex: ex
- Derivative of ln(x): 1/x (x > 0)
Higher-Order Derivatives
- A derivative of a derivative is a higher-order derivative.
- The second derivative is f''(x) or d2y/dx2, representing the rate of change of the rate of change.
- Higher-order derivatives are found by repeated application of differentiation rules.
Applications of Differentiation
- Finding tangent line slopes
- Locating critical points (local maxima and minima)
- Solving optimization problems (finding maximum or minimum values)
- Sketching curves
- Determining concavity and inflection points
- Calculating rates of change (including related rates problems)
