limit as x approaches infinity of 2x+1/x

x \to \infty lim (2 x + \frac{1}{x})

\infty

Solution steps

x \to \infty lim (2 x + \frac{1}{x})

x \to a lim [f (x) \pm g (x)] = x \to a lim f (x) \pm x \to a lim g (x)

With the exception of indeterminate form

= x \to \infty lim (2 x) + x \to \infty lim (\frac{1}{x})

x \to \infty lim (2 x) = \infty

x \to \infty lim (\frac{1}{x}) = 0

= \infty + 0

Apply Infinity Property:

\infty + c = \infty

= \infty

\int_{\frac{3}{2}}^{3} 9 - x^{2} d x

\frac{d}{d x} (cos (x^{2}))

\int_{0}^{3} \frac{1}{x ^{2} - x - 2} d x

x \to 3 lim (3 x^{2} - 2 x + 5)

\int \frac{sin ( x )}{cos ( x )} d x
