limit as x approaches-1-of (x+2x^3)^4

x \to - 1 - lim ((x + 2 x^{3})^{4})

81

Solution steps

x \to - 1 - lim ((x + 2 x^{3})^{4})

Plug in the value

x = - 1

= (- 1 + 2 (- 1)^{3})^{4}

Simplify

(- 1 + 2 (- 1)^{3})^{4} : 81

= 81

n = 0 \sum \infty (\frac{5}{5})^{n}

x y^{^{'}} + 5 y = x^{3} - x

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

\frac{\partial}{\partial s} (s \cdot cos (t))

f (x) = 6 cos (2 x)
