limit as x approaches 5 of sin((pix)/3)

解答

x \to 5 lim (sin (\frac{π x}{3}))

- \frac{3}{2}

十进制

- 0.86602 \dots

求解步骤

x \to 5 lim (sin (\frac{π x}{3}))

代入值

x = 5

= sin (\frac{π 5}{3})

化简

sin (\frac{π 5}{3}) : - \frac{3}{2}

= - \frac{3}{2}

(3 x^{2} - 2 x y) d x + (2 y - x^{2}) d y = 0

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

\int_{0}^{3} \frac{9}{x ^{2} + 9} d x

\int 5 π cos (π) x d x

\int (x^{1.7} + 11 x^{4.5}) d x
