integral of 5sin(6pix)

\int 5 sin (6 π x) d x

- \frac{5}{6 π} cos (6 π x) + C

Solution steps

\int 5 sin (6 π x) d x

Take the constant out:

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

= 5 \cdot \int sin (6 π x) d x

Apply u-substitution

: \int sin (u) \frac{1}{6 π} d u

= 5 \cdot \int sin (u) \frac{1}{6 π} d u

Take the constant out:

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

= 5 \cdot \frac{1}{6 π} \cdot \int sin (u) d u

Use the common integral:

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

= 5 \cdot \frac{1}{6 π} (- cos (u))

Substitute back

u = 6 π x

= 5 \cdot \frac{1}{6 π} (- cos (6 π x))

Simplify

5 \cdot \frac{1}{6 π} (- cos (6 π x)) : - \frac{5}{6 π} cos (6 π x)

= - \frac{5}{6 π} cos (6 π x)

Add a constant to the solution

= - \frac{5}{6 π} cos (6 π x) + C

ln ((5 x + 2) (3 x - 4)^{2})

y^{^{''}} - 4 y^{^{'}} + 4 y = x^{2}

(x + 1)^{\frac{1}{2}}

y^{^{'}} = 6 x (y - 1)^{\frac{2}{3}}

k = 0 \sum \infty \frac{k}{2 ^{k}} x^{k}
