limit as x approaches 1 of ((sin(x)))/x

解答

x \to 1 lim (\frac{( sin ( x ) )}{x})

sin (1)

十进制

0.84147 \dots

求解步骤

x \to 1 lim (\frac{sin ( x )}{x})

代入值

x = 1

= \frac{sin ( 1 )}{1}

化简

= sin (1)

y^{^{'}} sin (x) = y ln (y)

d er i v a t i v e f (x) = \frac{x ^{2} - 1}{( x + 1 ) ^{2}}

ma c l a u r in ln (1 + 4 x)

\int \frac{3 x}{1 - x} d x

\int \frac{( x ^{2} - 4 ) ^{\frac{5}{2}}}{x} d x
