integral of (y+1)/(2sqrt(y))

\int \frac{y + 1}{2 y} d y

\frac{1}{3} y (y + 3) + C

Solution steps

\int \frac{y + 1}{2 y} d y

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{y + 1}{y} d y

Expand

\frac{y + 1}{y} : y + \frac{1}{y}

= \frac{1}{2} \cdot \int y + \frac{1}{y} 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

= \frac{1}{2} (\int y d y + \int \frac{1}{y} d y)

\int y d y = \frac{2}{3} y^{\frac{3}{2}}

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

= \frac{1}{2} (\frac{2}{3} y^{\frac{3}{2}} + 2 y)

Simplify

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

= \frac{1}{3} y (y + 3)

Add a constant to the solution

= \frac{1}{3} y (y + 3) + C

f (x) = (3 x + 1), at a = 1

f (x) = 4 x - \frac{8}{x}

x \to 1 lim (\frac{7}{1 - x})

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

\int \frac{4 + cos ( x )}{x ^{2}} d x
