Study Notes
Overview of Calculus
- Calculus is the mathematical study of continuous change.
- Two main branches: Differential Calculus and Integral Calculus.
Differential Calculus
- Concerned with the concept of the derivative.
- Derivative: Measures the rate of change of a function.
- Notation: f'(x), df/dx.
- Fundamental Rules:
- Power Rule: d/dx[x^n] = nx^(n-1)
- Product Rule: d/dx[uv] = u'v + uv'
- Quotient Rule: d/dx[u/v] = (u'v - uv')/v^2
- Chain Rule: d/dx[f(g(x))] = f'(g(x)) * g'(x)
Integral Calculus
- Concerned with the concept of the integral.
- Integral: Represents accumulation of quantities, such as areas under curves.
- Notation: ∫f(x)dx.
- Fundamental Theorem of Calculus:
- Connects differentiation and integration.
- If F is an antiderivative of f, then ∫f(x)dx = F(b) - F(a).
- Techniques of Integration:
- Substitution: Simplifies integrals by changing variables.
- Integration by Parts: ∫u dv = uv - ∫v du.
- Partial Fractions: Decomposes rational functions into simpler fractions.
Limits
- Fundamental concept in calculus; defines the behavior of functions as they approach a point.
- Notation: lim (x→c) f(x).
- Key Properties:
- Limit of a sum: lim (x→c) [f(x) + g(x)] = lim (x→c) f(x) + lim (x→c) g(x).
- Limit of a product: lim (x→c) [f(x) * g(x)] = lim (x→c) f(x) * lim (x→c) g(x).
Applications of Calculus
- Optimization: Finding maximum or minimum values of functions.
- Motion Analysis: Understanding velocity and acceleration through derivatives and integrals.
- Area and Volume: Calculating areas under curves and volumes of solids of revolution.
Key Concepts
- Continuous Functions: Functions without breaks, jumps, or holes.
- Inflection Points: Points where the curve changes concavity.
- Asymptotes: Lines that a graph approaches but never touches.
Overview of Calculus
- A mathematical field focused on studying continuous change.
- Comprised of two primary branches: Differential Calculus and Integral Calculus.
Differential Calculus
- Deals with derivatives, which quantify how a function changes.
- Derivative notation includes f'(x) and df/dx.
- Fundamental differentiation rules include:
- Power Rule: For any term x^n, the derivative is nx^(n-1).
- Product Rule: For functions u and v, (\frac{d}{dx}[uv] = u'v + uv').
- Quotient Rule: For functions u and v, (\frac{d}{dx}[u/v] = \frac{(u'v - uv')}{v^2}).
- Chain Rule: For composite functions, (\frac{d}{dx}[f(g(x))] = f'(g(x)) \cdot g'(x)).
Integral Calculus
- Focuses on integrals, indicating the accumulation of quantities, often areas under curves.
- Integral notation is expressed as ∫f(x)dx.
- The Fundamental Theorem of Calculus links differentiation and integration, stating if F is an antiderivative of f, then ∫f(x)dx = F(b) - F(a).
- Key techniques for integration include:
- Substitution: Changing variables to simplify the integral.
- Integration by Parts: Using the formula ∫u dv = uv - ∫v du to break down integrals.
- Partial Fractions: Breaking rational functions into simpler fractions for easier integration.
Limits
- A foundational concept in calculus that determines function behavior as inputs approach a specified point.
- Notation used is lim (x→c) f(x).
- Key limit properties include:
- Limit of a Sum: lim (x→c) [f(x) + g(x)] = lim (x→c) f(x) + lim (x→c) g(x).
- Limit of a Product: lim (x→c) [f(x) * g(x)] = lim (x→c) f(x) * lim (x→c) g(x).
Applications of Calculus
- Optimization: Techniques used to find the maximum or minimum values of functions.
- Motion Analysis: Utilizes derivatives and integrals to analyze velocity and acceleration.
- Area and Volume Calculations: Techniques to compute areas under curves and the volumes of solids of revolution.
Key Concepts
- Continuous Functions: Functions that do not have breaks, jumps, or discontinuities.
- Inflection Points: Points on a curve where the curvature changes from concave up to concave down, or vice versa.
- Asymptotes: Lines that a graph approaches arbitrarily closely but never intersects.
