limit as θ approaches 0 of (sin(θ))/θ

解答

θ \to 0 lim (\frac{sin ( θ )}{θ})

1

求解步骤

θ \to 0 lim (\frac{sin ( θ )}{θ})

使用洛必达法则

= θ \to 0 lim (\frac{cos ( θ )}{1})

代入值

θ = 0

= \frac{cos ( 0 )}{1}

化简

\frac{cos ( 0 )}{1} : 1

= 1

\frac{d}{d x} (ln (x + 10))

d er i v a t i v e e^{- 3 x} + e^{4 x}

x \to 2 lim (2 x^{2} + 6)

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

e x p an d \frac{3}{x ( x + 1 ) ^{2}}
