limit as x approaches pi of sin(x/2-pi)

解答

x \to π lim (sin (\frac{x}{2} - π))

- 1

求解步骤

x \to π lim (sin (\frac{x}{2} - π))

代入值

x = π

= sin (\frac{π}{2} - π)

化简

sin (\frac{π}{2} - π) : - 1

= - 1

p \to 2 lim (p^{2} + p + 5)

x \to \infty lim ((- 5)^{n})

x \to - 2 lim ((x + 4) (x - \frac{1}{2}))

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

x \to 0 lim (\frac{0}{sin ^{2} ( x )})
