verifica las siguientes integrales​

Answer 1

Explicación paso a paso:

29.

$v = 3x \\dv = 3dx \\ \frac{dv}{3} = dx$

$\gamma \sin(3x) dx =$

$\frac{1}{3} \gamma \sin(v) dv =$

$\frac{1}{3} \times ( \ - cos(v)) + c=$

$- \frac{1}{3} \times \cos(3x) + c$ ◇

30.

{tan (2x + 3) dx

= 1/2 { tan (v) dv

= 1/2 { (sen v / cos v ) dv

= 1/2 { (- 1 / u ) dv

= - 1/2 { ( 1 / u ) dv

= - 1/2 ln | cos (2x + 3) | + c ◇

v = 2x + 3

dv = 2dx

u = cos(u)

du = -sen(u) du
