limit as x approaches 3 of x^3-3x^2-9x

x \to 3 lim (x^{3} - 3 x^{2} - 9 x)

- 27

Solution steps

x \to 3 lim (x^{3} - 3 x^{2} - 9 x)

Plug in the value

x = 3

= 3^{3} - 3 \cdot 3^{2} - 9 \cdot 3

Simplify

3^{3} - 3 \cdot 3^{2} - 9 \cdot 3 : - 27

= - 27

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

\int \frac{z ^{- 3}}{3} d z

y^{^{''}} + 16 y = 2 tan (4 x)

x \to - 1 lim (2 x)

\int_{0}^{π} cos (n x) d x
