Summary: Ejercicio resuelto por el método de integración por partes

Integración por partes

Ejemplo:

x²dx1+x = 215 (3x²-4x+8) x+1 + C Fórmula de Integración por partes:

udv = uv-v du

Desarrollo:

u= X² dv= 1 1+xdx

du= 2x v=11+xdx= dww= w-1/2dw = 2w1/2+ C = 21+x + C

w= 1+x

dw= dx

= X²2 (1+X)1/2 - ∫2(1+X)1/22xdx

=2x² (1+X)1/2 - 4 x(1+X)1/2dx

u= X dv= (1+X)1/2

du= dx v= (1+X)1/2dx= (1+X)3/23/2 + C= 23(1+X)3/2 + C

=2x² (1+x)1/2 - 4[ x (23 (1+X)3/2- 23(1+X)3/2dx]

=2x² (1+x)1/2 - 4[ x (23 (1+X)3/2- 23(1+X)3/2dx]

=2x² (1+x)1/2 - 83 x (1+X)3/2 + 83 (25(1+X)5/2 + C

=2x² (1+x)1/2 - 83 x (1+X)3/2 + 1615 (1+X)5/2 + C

=(1+x)1/2 [2x²- 83 x (1+X) + 1615 (1+ 2x + x²)] + C

=(1+x)1/2 [2x²- 83 (1+X²) + 1615 (1+ 2x + x²)] + C

= 1+X [2x² - 83 x - 83 x² + 1615 + 3215 x + 1615 x²] + C

=1+X [3015 x² - 4015x - 4015x²+ 1615 + 3215 x + 1615 x²] + C

=1+X [1615 x²- 815x + 1615] + C =1+X215 [3x² - 4x + 8] + C Resultado

What is an EPUB file?

EPUB is an electronic book format that can be read on a variety of mobile devices.

My Favorites (?)

'My Favorites' is a special kind of lens which you can use to bookmark modules and collections. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need an account to use 'My Favorites'.

Definition of a lens

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags?

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
