limit as x approaches pi of xcos((7x)/6)

x \to π lim (x cos (\frac{7 x}{6}))

- π \frac{3}{2}

Decimal Notation

- 2.72069 \dots

Solution steps

x \to π lim (x cos (\frac{7 x}{6}))

Plug in the value

x = π

= π cos (\frac{7 π}{6})

Simplify

π cos (\frac{7 π}{6}) : - π \frac{3}{2}

= - π \frac{3}{2}

\frac{x}{x + 6}

\int - \frac{2}{7 - 7 x ^{2}} d x

\frac{d}{d x} (5 x^{3} - 3 x^{5})

t \to - 2 lim ((t + 4)^{2})

x \to - 1 lim (5 x^{2})

What is the limit as x approaches pi of xcos((7x)/6) ?
The limit as x approaches pi of xcos((7x)/6) is -pi(sqrt(3))/2
