limit as x approaches-4pi of sqrt(x+15)cos(x+4pi)

x \to - 4 π lim (x + 15 cos (x + 4 π))

- 4 π + 15

Decimal

1.56000 \dots

Solution steps

x \to - 4 π lim (x + 15 cos (x + 4 π))

Plug in the value

x = - 4 π

= - 4 π + 15 cos (- 4 π + 4 π)

Simplify

- 4 π + 15 cos (- 4 π + 4 π) : - 4 π + 15

= - 4 π + 15

x \to - 4 lim (8 x + 1)

\int x^{4} e^{8 x^{5}} d x

f (x) = e^{3}

f (x) = x^{5}, (1, 1)

\frac{d}{d x} (sec (x) tan (y))
