integral from 2 to 4 of 3x

\int_{2}^{4} 3 x d x

18

Solution steps

\int_{2}^{4} 3 x d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 3 \cdot \int_{2}^{4} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{2}^{4}

= 3 [\frac{x ^{2}}{2}]_{2}^{4}

Compute the boundaries:

6

= 3 \cdot 6

Simplify

= 18

\frac{\partial}{\partial x} (arctan (2 x))

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

\frac{d}{d x} (7 x + 3)

\frac{d}{d x} (- \frac{192}{x ^{4}})

(3 + sin (2 x))^{2}
