xdy=dx

Solution

x d y = d x

Solution

y = ln (x) + c_{1}

Solution steps

x d y = d x

Let

y

be the dependent variable. Divide by

d x

:

x \frac{d y}{d x} = 1

Substitute

\frac{d y}{d x}

with

y^{'} (x)

x y^{^{'}} (x) = 1

Isolate

y^{'} (x) : y^{'} (x) = \frac{1}{x}

If

f^{^{'}} (x) = g (x)

then

f (x) = \int g (x) d x

y = \int \frac{1}{x} d x

\int \frac{1}{x} d x = ln (x) + c_{1}

y = ln (x) + c_{1}
