limit as x approaches 3 of (1/3 sqrt(x)-sqrt(1/3))/(x-3)

x \to 3 lim \frac{\frac{1}{3} x - \frac{1}{3}}{x - 3}

\frac{1}{6 3}

Decimal Notation

0.09622 \dots

Solution steps

x \to 3 lim \frac{\frac{1}{3} x - \frac{1}{3}}{x - 3}

Multiply by the conjugate of

\frac{1}{3} x - \frac{1}{3} : \frac{\frac{1}{9} x - \frac{1}{3}}{\frac{1}{3} x + \frac{1}{3}}

= x \to 3 lim \frac{\frac{\frac{1}{9} x - \frac{1}{3}}{\frac{1}{3} x + \frac{1}{3}}}{x - 3}

Simplify

\frac{\frac{\frac{1}{9} x - \frac{1}{3}}{\frac{1}{3} x + \frac{1}{3}}}{x - 3} : \frac{1}{3 ( x + 3 )}

= x \to 3 lim (\frac{1}{3 ( x + 3 )})

Plug in the value

x = 3

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

Simplify

= \frac{1}{6 3}

8 cos (x)

2 t + 1

x \to \infty lim (x^{2} - 25)

\frac{d y}{d x} + 8 y = 6

2 - t
