Giải các phương trình vi phân sau y' - y/x+1 = 2

KatRina [158]

It looks like the differential equation is

$y'-\dfrac y{x+1}=2$

Multiply both sides by 1/(x + 1) :

$\dfrac{y'}{x+1}-\dfrac y{(x+1)^2} = \dfrac2{x+1}$

The left side is now a derivative of a product,

$\left(\dfrac y{x+1}\right)' = \dfrac2{x+1}$

Integrate both sides with respect to x :

$\dfrac y{x+1} = 2\ln|x+1|+C$

Solve for y :

$y = 2(x+1)\ln|x+1| + C(x+1)$

What is 5/7+3/4 in simplest forms

Ira Lisetskai [31]

$\frac{5}{7} + \frac{3}{4} = \frac{5\times 4}{7\times 4}+\frac{3\times 7}{4\times 7}=\frac{20}{28}+\frac{21}{28}=\frac{20+21}{28} = \frac{41}{28} = \boxed{1\frac{13}{28}}$
