Study Notes
Calculus
Definition
- Branch of mathematics focused on rates of change (differentiation) and accumulation of quantities (integration).
Key Concepts
-
Limits
- Fundamental concept for defining derivatives and integrals.
- Notation: lim (x → a) f(x).
- Understanding continuity and discontinuity.
-
Derivatives
- Measures the rate of change of a function with respect to a variable.
- Notation: f'(x) or df/dx.
- Basic 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
