limit as x approaches 0+of 9cos(9x)

x \to 0 + lim (9 cos (9 x))

9

Solution steps

x \to 0 + lim (9 cos (9 x))

Plug in the value

x = 0

= 9 cos (9 \cdot 0)

Simplify

9 cos (9 \cdot 0) : 9

= 9

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

x \to 0 lim (- 4 x^{- 3})

\frac{d}{d x} (arctan (\frac{a ^{2} - x ^{3}}{b ^{2}}))

\int_{1}^{\infty} \frac{x}{x ^{2} + 1} d x

\frac{\partial}{\partial y} (x y^{2} e^{x^{2}})
