limit as x approaches 3 of 4/(x^2+2x+3)

x \to 3 lim (\frac{4}{x ^{2} + 2 x + 3})

\frac{2}{9}

Decimal Notation

0.22222 \dots

Solution steps

x \to 3 lim (\frac{4}{x ^{2} + 2 x + 3})

Plug in the value

x = 3

= \frac{4}{3 ^{2} + 2 \cdot 3 + 3}

Simplify

\frac{4}{3 ^{2} + 2 \cdot 3 + 3} : \frac{2}{9}

= \frac{2}{9}

\frac{d}{d x} (14 - \frac{1}{2} x^{- 3})

y = arcsin (8 x + 1)

\frac{d}{d x} (cos^{2} (2 x^{4} - 4))

\int \frac{sec ^{4} ( x )}{tan ^{3} ( x )} d x

\int (x - 5) cos (x) d x
