\int_{0}^{9} 1

9

Solution steps

\int_{0}^{9} 1 d x

Integral of a constant:

\int a d x = a x

= [1 \cdot x]_{0}^{9}

Simplify

= [x]_{0}^{9}

Compute the boundaries:

9

= 9

\int_{0}^{\frac{π}{6}} tan (x) d x

\int_{0}^{5} (u^{2} + u + 1) d u

\int_{- π}^{0} - 3 cos^{2} (x) sin (x) d x

\int_{- 4}^{6} ∣ x ∣ d x

\int_{- 2}^{- 1} (x^{2} + \frac{1}{x ^{2}}) d x
