integral from 3 to 7 of 6+2ln(t+8)

\int_{3}^{7} 6 + 2 ln (t + 8) d t

16 + 30 ln (15) - 22 ln (11)

Decimal

44.48781 \dots

Solution steps

\int_{3}^{7} 6 + 2 ln (t + 8) d t

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}^{7} 6 d t + \int_{3}^{7} 2 ln (t + 8) d t

\int_{3}^{7} 6 d t = 24

\int_{3}^{7} 2 ln (t + 8) d t = 2 (15 ln (15) - 4 - 11 ln (11))

= 24 + 2 (15 ln (15) - 4 - 11 ln (11))

Simplify

24 + 2 (15 ln (15) - 4 - 11 ln (11)) : 16 + 30 ln (15) - 22 ln (11)

= 16 + 30 ln (15) - 22 ln (11)

\int_{0}^{2} (3 x + 2) d x

\int_{0}^{t a n (θ)} cos (x) d x

\int_{4}^{5} e^{4 - x} d x

\int_{1}^{e^{5}} \frac{6 ln ( x )}{x} d x

\int_{x^{3}}^{x^{4}} (2 t - 6)^{6} d t
