integral of (sin(sqrt(x))*cos(sqrt(x)))/(sqrt(x))

\int \frac{sin ( x ) \cdot cos ( x )}{x} d x

- \frac{1}{2} cos (2 x) + C

Solution steps

\int \frac{sin ( x ) cos ( x )}{x} d x

Rewrite using trig identities

= \int \frac{sin ( 2 x )}{2 x} d x

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{sin ( 2 x )}{x} d x

Apply u-substitution

: \int sin (u) d u

= \frac{1}{2} \cdot \int sin (u) d u

Use the common integral:

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

= \frac{1}{2} (- cos (u))

Substitute back

u = 2 x

= \frac{1}{2} (- cos (2 x))

Simplify

= - \frac{1}{2} cos (2 x)

Add a constant to the solution

= - \frac{1}{2} cos (2 x) + C

\int \frac{1}{- 196.2 - 4 v ^{2}} d v

x \to \infty lim (\frac{4}{x})

x \to 0 lim ((tan (3 x))^{x})

\frac{d}{d x} (\frac{2}{x})

n = 1 \sum \infty \frac{1}{7 n + 7}
