limit as x approaches 0 of (sin(1))/1

解答

x \to 0 lim (\frac{sin ( 1 )}{1})

sin (1)

十进制

0.84147 \dots

求解步骤

x \to 0 lim (\frac{sin ( 1 )}{1})

x \to a lim c = c

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

化简

= sin (1)

2 \frac{d y}{d x} + \frac{y}{x} = x^{2} y^{- 1}

t an g e n t 9 x + 2 x^{2}

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

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

\frac{d}{d x} (\frac{1}{8} x - ln (2 x))
