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

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

2 Si (x y) + C

Solution steps

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

Apply u-substitution

= \int \frac{sin ( u )}{u} d u

Apply u-substitution

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

Take the constant out:

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

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

Use the nonelementary integral:

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

= 2 Si (v)

Substitute back

= 2 Si (x y)

Add a constant to the solution

= 2 Si (x y) + C

\int x (x + \frac{2}{x ^{3}}) d x

\int t + 3 d t

\int (2 x^{6} + x^{2} - x - 2) d x

\int \frac{1}{( 529 + x ^{2} ) ^{\frac{3}{2}}} d x

\int \frac{lo g _{10} ( x )}{x ^{3}} d x
