limit as x approaches 0.9 of x^2-1

x \to 0.9 lim (x^{2} - 1)

- 0.19

Solution steps

x \to 0.9 lim (x^{2} - 1)

Plug in the value

x = 0.9

= 0. 9^{2} - 1

Simplify

= - 0.19

y = 13 x e^{x}

\frac{d y}{d x} - \frac{2 x ^{3} y}{x ^{4} + 3} = x^{3}

\frac{d}{d x} (2 A x + B)

\frac{d}{d x} (x^{6} ln (5 x))

\frac{d}{d x} (\frac{1}{x ^{2} + 2 y ^{2} - 5})
