limit as x approaches 6-of tan((pix)/4)

解答

x \to 6 - lim (tan (\frac{π x}{4}))

\infty

求解步骤

x \to 6 - lim (tan (\frac{π x}{4}))

使用极限链式法则:

\infty

= \infty

\int \frac{1}{x ( x ^{3} + 1 )} d x

a re a y = e^{3 x}, x = 0, x = 3

d er i v a t i v e f (x) = (x + 1)^{3} (x + 4) (x - 3)^{2}

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

t an g e n t f (x) = 4 x^{2} - 5 x, at x = - 1
