dx+e^{7x}dy=0

d x + e^{7 x} d y = 0

y = \frac{1}{7} e^{- 7 x} + c_{1}

Solution steps

d x + e^{7 x} d y = 0

Let

y

be the dependent variable. Divide by

d x

1 + e^{7 x} \frac{d y}{d x} = 0

Substitute

\frac{d y}{d x}

with

y^{'} (x)

1 + e^{7 x} y^{^{'}} (x) = 0

Isolate

y^{'} (x) : y^{'} (x) = - \frac{1}{e ^{7 x}}

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

then

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

y = \int - \frac{1}{e ^{7 x}} d x

\int - \frac{1}{e ^{7 x}} d x = \frac{1}{7} e^{- 7 x} + c_{1}

y = \frac{1}{7} e^{- 7 x} + c_{1}

y^{^{''}} + 4 y = x^{2} sin (2 x)

\int (e^{- x} + e^{x})^{2} d x

\int 10 sin^{3} (x co) s^{5} x d x

\frac{1}{s ^{2} - 9}

(2 x - 4)^{4} (x^{2} + x + 1)^{5}
