limit as x approaches 1 of [f(x)+5g(x)]

解答

x \to 1 lim ([f (x) + 5 g (x)])

f (1) + 5 g (1)

求解步骤

x \to 1 lim (f (x) + 5 g (x))

Plug in the value

x = 1

, assuming the function is continuous at this point

= f (1) + 5 g (1)

x + y \frac{d y}{d x} = x - y

t an g e n t f (x) = x^{3} - x, (1, 0)

n = 0 \sum \infty \frac{1}{n ( n + 8 )}

in v erse l a pl a ce \frac{5}{s \cdot ( 2 \cdot s + 1 )}

3 y^{^{'}} - 6 y = 12, y (0) = 4
