limit as x approaches 3 of sqrt(2x^2-2)

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

4

Solution steps

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

Plug in the value

x = 3

= 2 \cdot 3^{2} - 2

Simplify

2 \cdot 3^{2} - 2 : 4

= 4

\frac{d y}{d x} + y^{7} x + y = 0

\frac{d}{d x} (\frac{3 cos ( x )}{1 - 2 sin ( x )})

\frac{\partial}{\partial v} (\frac{u - v}{3})

\int \frac{e ^{x}}{e ^{x} + 1} d x

3 cos (2 x), (3 - 3 cos (2 x)) x = 0 x = \frac{π}{2}
