limit as x approaches 4 of sqrt(x^3+4x)

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

45

Decimal

8.94427 \dots

Solution steps

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

Plug in the value

x = 4

= 4^{3} + 4 \cdot 4

Simplify

4^{3} + 4 \cdot 4 : 45

= 45

\frac{d y}{d x}, x = cos (2 y)

x \to 0 lim (\frac{5}{2} x^{2})

\int sin (x) sin (\frac{2 x}{3}) d x

\frac{d}{d x} (e^{a (e^{x} - 1)})

\frac{1}{s}
