Study Notes
Multivariable Integral Calculus I
- Double Integrals: Utilisation de duo integralos para calcular areas e volumines in multidimensional space.
Cartesian Coordinates
- Definition de double integral in Cartesian coordinates: ∫∫f(x,y)dxdy
- Evaluation of double integral in Cartesian coordinates: f(x,y) es integrado primeiro con respecto a x, puis con respecto a y
Change of Order of Integration
- Theorem: ∫∫f(x,y)dxdy = ∫∫f(x,y)dydx (change of order of integration)
- Importance: permite de evaluar double integral in different ways
Change of Variables (Cartesian to Polar Coordinates)
- Definition: transformation de coordenadas Cartesianas (x,y) to coordenadas polares (r,θ)
- Jacobian: determinante de la matriz de transformation, utilisé pour changer de variables
Evaluation of Area by Double Integration
- Formula: Area = ∫∫dxdy (area enclosed by a curve)
- Application: Calculation of area of complex shapes using double integration
Multivariable Integral Calculus I
- Double Integrals: used to calculate area or volume of a region in Cartesian coordinates
Cartesian Coordinates
- Evaluation of area by Double Integration: calculates the area of a region by integrating a function with respect to both x and y variables
- Change of Order of Integration: allows rearrangement of the order of integration, i.e., integrating first with respect to x and then with respect to y, or vice versa
Change of Variables
- Cartesian to polar coordinates: transformation of coordinates from Cartesian (x, y) to polar (r, θ) coordinates
- Allows for evaluation of double integrals in polar coordinates, facilitating calculations for areas and volumes of regions with circular or radial symmetry
Area Entre Curvas
- Le area entre duo curvas pote esser trovate per integrar le differentia entre le duo functiones con respecto a x.
- Le formula pro le area entre duo curvas es: ∫[a, b] (f(x) - g(x)) dx
- Le curvas debe esser continue e intersectar se al limites de integration.
- Le area es trovate per subtracter le area sous le curva inferior desde le area sous le curva superior.
Exemplos de Area Entre Curvas
- Trovar le area entre le curvas y = x^2 e y = x desde x = 0 a x = 1: ∫[0, 1] (x - x^2) dx = 1/6
- Trovar le area entre le curvas y = 2x e y = x^2 desde x = 0 a x = 2: ∫[0, 2] (2x - x^2) dx = 8/3
Coordinatas Polar
- Coordinatas polar es usate pro trovar le area de un region limitate per un curva polar.
- Le formula pro le area de un region limitate per un curva polar es: (1/2) ∫[α, β] (r^2) dθ
