limit as x approaches 0 of (x^3+7x)/x

x \to 0 lim (\frac{x ^{3} + 7 x}{x})

7

Solution steps

x \to 0 lim (\frac{x ^{3} + 7 x}{x})

Simplify

\frac{x ^{3} + 7 x}{x} : x^{2} + 7

= x \to 0 lim (x^{2} + 7)

Plug in the value

x = 0

= 0^{2} + 7

Simplify

= 7

y = x^{2} - 5, y = 4

\int_{6}^{8} \frac{64}{( x - 6 ) ^{3}} d x

\int x cos (3 x + 1) d x

\int sin^{7} (3 x) d x

\frac{d}{d x} (5 ln (6 - x^{2}))
