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

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

256

Solution steps

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

Plug in the value

x = - 1

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

Simplify

(- 1 + 3 (- 1)^{3})^{4} : 256

= 256

y^{^{'}} = e^{x + y}

y^{^{''}} + 2 y^{^{'}} - 3 y = 0, y (0) = 1, y^{^{'}} (0) = 1

y = x e^{3 x}

\int 1 + t^{3} d t

n = 0 \sum \infty (- 1)^{n} (- 2)^{n}
