(\partial)/(\partial x)(9xln(x)y)

\frac{\partial}{\partial x} (9 x ln (x) y)

9 y (ln (x) + 1)

Solution steps

\frac{\partial}{\partial x} (9 x ln (x) y)

Treat

y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 9 y \frac{\partial}{\partial x} (x ln (x))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = ln (x)

= 9 y (\frac{\partial}{\partial x} (x) ln (x) + \frac{\partial}{\partial x} (ln (x)) x)

\frac{\partial}{\partial x} (x) = 1

\frac{\partial}{\partial x} (ln (x)) = \frac{1}{x}

= 9 y (1 \cdot ln (x) + \frac{1}{x} x)

Simplify

9 y (1 \cdot ln (x) + \frac{1}{x} x) : 9 y (ln (x) + 1)

= 9 y (ln (x) + 1)

(- 4 - 4) (- 4 - 9)

t \cdot y^{^{'}} = y + ((\frac{1}{4}) \cdot t^{2} + y^{2})^{(\frac{1}{2})}

\int \frac{1}{x 9 - 16 x ^{2}} d x

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

\int_{\frac{x}{z}}^{1} 1 d y
