integral from 0 to 1 of 3t^2sin(t^3)

\int_{0}^{1} 3 t^{2} sin (t^{3}) d t

- cos (1) + 1

Decimal

0.45969 \dots

Solution steps

\int_{0}^{1} 3 t^{2} sin (t^{3}) d t

Take the constant out:

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

= 3 \cdot \int_{0}^{1} t^{2} sin (t^{3}) d t

Apply u-substitution

: \int_{0}^{1} \frac{sin ( u )}{3} d u

= 3 \cdot \int_{0}^{1} \frac{sin ( u )}{3} d u

Take the constant out:

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

= 3 \cdot \frac{1}{3} \cdot \int_{0}^{1} sin (u) d u

Use the common integral:

\int sin (u) d u = - cos (u)

= 3 \cdot \frac{1}{3} [- cos (u)]_{0}^{1}

Simplify

3 \cdot \frac{1}{3} [- cos (u)]_{0}^{1} : [- cos (u)]_{0}^{1}

= [- cos (u)]_{0}^{1}

Compute the boundaries:

- cos (1) + 1

= - cos (1) + 1

\int_{1}^{e} \frac{( ln ( x ^{4} ) )}{x} d x

\int_{1}^{l n (8)} e^{y} (y - 1) d y

\int_{- 2}^{1} 4 x + 8 d x

\int_{0}^{1} (3 x) d x

\int_{- 3}^{2} - 3 ∣ x ∣ d x
