limit as x approaches 4 of x/(4-x)-x^3

x \to 4 lim (\frac{x}{4 - x} - x^{3})

diverges

Solution steps

x \to 4 lim (\frac{x}{4 - x} - x^{3})

x \to a - lim f (x) \neq = x \to a + lim f (x)

then the limit does not exist

x \to 4 + lim (\frac{x}{4 - x} - x^{3}) = - \infty

x \to 4 - lim (\frac{x}{4 - x} - x^{3}) = \infty

= diverges

y^{^{''}} + 8 y^{^{'}} + 15 y = cos (x)

f (x) = 3 x cos (x), (π, - 3 π)

(1 - e^{- x} - x e^{- x})^{^{'}}

\frac{\partial}{\partial x} (x^{3} y - x)

\int \frac{x ^{2} + 1}{x ^{3} + 3 x} d x
