integral of 7/(2x)

\int \frac{7}{2 x} d x

\frac{7}{2} ln ∣ x ∣ + C

Solution steps

\int \frac{7}{2 x} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{7}{2} \cdot \int \frac{1}{x} d x

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= \frac{7}{2} ln ∣ x ∣

Add a constant to the solution

= \frac{7}{2} ln ∣ x ∣ + C

y^{^{'}} = \frac{( x ^{2} y ^{4} + 3 x ^{2} )}{y ^{3}}

\frac{\partial}{\partial y} (x^{2} y^{2} - x)

3 + t^{5} + sin (π t)

\int 6 sin^{3} (x) cos^{7} (x) d x

\frac{2 s ^{2} + 5 s + 7}{( s + 1 ) ^{3}}
