limit as x approaches pi/6 of cos(-5x)

x \to \frac{π}{6} lim (cos (- 5 x))

- \frac{3}{2}

Solution steps

x \to \frac{π}{6} lim (cos (- 5 x))

Plug in the value

x = \frac{π}{6}

= cos (- 5 \cdot \frac{π}{6})

Simplify

cos (- 5 \cdot \frac{π}{6}) : - \frac{3}{2}

= - \frac{3}{2}

x^{2} e^{3 x}, - 2

\int \frac{x + 6}{x ^{2} + 25} d x

\int \frac{x ^{2}}{4 x - x ^{2}} d x

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

8 cos (t)
