limit as x approaches 7 of 5x^{-1}

x \to 7 lim (5 x^{- 1})

\frac{5}{7}

Decimal Notation

0.71428 \dots

Solution steps

x \to 7 lim (5 x^{- 1})

Plug in the value

x = 7

= 5 \cdot 7^{- 1}

Simplify

5 \cdot 7^{- 1} : \frac{5}{7}

= \frac{5}{7}

\int \frac{x}{x ^{2} - 2 x - 3} d x

x \to 1 lim (\frac{x ^{4} - 1}{x ^{3} - 1})

3 x - 32 x, at x = 4

y = x^{2} - 12, y = x - 6

\frac{\partial}{\partial x} (x + \frac{x - y}{y - z})
