integral of (((y^3-1))/y)^2

\int (\frac{( y ^{3} - 1 )}{y})^{2} d y

\frac{y ^{5}}{5} - y^{2} - \frac{1}{y} + C

Solution steps

\int (\frac{y ^{3} - 1}{y})^{2} d y

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \int \frac{( y ^{3} - 1 ) ^{2}}{y ^{2}} d y

Expand

\frac{( y ^{3} - 1 ) ^{2}}{y ^{2}} : y^{4} - 2 y + \frac{1}{y ^{2}}

= \int y^{4} - 2 y + \frac{1}{y ^{2}} d y

Apply the Sum Rule:

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

= \int y^{4} d y - \int 2 y d y + \int \frac{1}{y ^{2}} d y

\int y^{4} d y = \frac{y ^{5}}{5}

\int 2 y d y = y^{2}

\int \frac{1}{y ^{2}} d y = - \frac{1}{y}

= \frac{y ^{5}}{5} - y^{2} - \frac{1}{y}

Add a constant to the solution

= \frac{y ^{5}}{5} - y^{2} - \frac{1}{y} + C

\int \frac{8}{( x + 3 ) ^{4}} d x

\int 3 x sec^{2} (x^{2}) d x

\int cos^{12} (7 t) sin (7 t) d t

\int \frac{1}{2 x ^{2} - 2 + 1} d x

\int (z + 7) e^{8 z} d z
