šŸ”‘ Core Calculus Concepts

šŸŽÆ Limits

  • Limit Definition: The value a function approaches as input approaches a value
  • One-sided Limits: Left and right hand limits
  • Infinity Limits: Behavior as x approaches Ā±āˆž
  • Continuity: No breaks, holes, or jumps in the function

šŸ“ˆ Derivatives

  • Definition: Rate of change, slope of tangent line
  • Notation: f'(x), dy/dx, d/dx[f(x)]
  • Power Rule: d/dx[x^n] = nx^(n-1)
  • Chain Rule: d/dx[f(g(x))] = f'(g(x)) Ɨ g'(x)
  • Product Rule: d/dx[uv] = u'v + uv'
  • Quotient Rule: d/dx[u/v] = (u'v - uv')/v²

∫ Integrals

  • Antiderivative: Reverse process of differentiation
  • Definite Integral: Area under curve between limits
  • Fundamental Theorem: Links derivatives and integrals
  • Integration Rules: Power, substitution, parts

āˆ‘ Series

  • Sequences: Ordered list of numbers
  • Series: Sum of sequence terms
  • Convergence: Series approaches a finite limit
  • Divergence: Series grows without bound

šŸ›ļø Fundamental Calculus Theorems

Fundamental Theorem of Calculus

Links differentiation and integration

Part 1: \frac{d}{dx}\int_a^x f(t) \, dt = f(x)

Part 2: \int_a^b f(x) \, dx = F(b) - F(a)

Mean Value Theorem

Guarantees a point where instantaneous rate equals average rate

f'(c) = \frac{f(b) - f(a)}{b - a} for some c in (a,b)

Intermediate Value Theorem

Continuous functions take every value between f(a) and f(b)

If f(a) < k < f(b), then ∃c in (a,b) such that f(c) = k

Taylor Series

Represents functions as infinite polynomials

f(x) = \sum_{n=0}^{\infty} \frac{f^{(n)}(a)}{n!}(x-a)^n
