integral of 3x-1/x-7e^x+14e

\int 3 x - \frac{1}{x} - 7 e^{x} + 14 e d x

\frac{3 x ^{2}}{2} - ln ∣ x ∣ - 7 e^{x} + 14 e x + C

Solution steps

\int 3 x - \frac{1}{x} - 7 e^{x} + 14 e d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 3 x d x - \int \frac{1}{x} d x - \int 7 e^{x} d x + \int 14 e d x

\int 3 x d x = \frac{3 x ^{2}}{2}

\int \frac{1}{x} d x = ln ∣ x ∣

\int 7 e^{x} d x = 7 e^{x}

\int 14 e d x = 14 e x

= \frac{3 x ^{2}}{2} - ln ∣ x ∣ - 7 e^{x} + 14 e x

Add a constant to the solution

= \frac{3 x ^{2}}{2} - ln ∣ x ∣ - 7 e^{x} + 14 e x + C

\frac{5}{x}, at x = 2

\int_{0}^{9} \frac{10}{( 1 + x ) ^{2}} d x

x \to - 3 lim (ln (x + 3))

cos (x^{2} - 4 x + 3)

\int \frac{t}{e ^{2 t}} d t
