integral of (3(sin(2x))/(sin(x)))

\int (3 \frac{sin ( 2 x )}{sin ( x )}) d x

6 sin (x) + C

Solution steps

\int 3 \cdot \frac{sin ( 2 x )}{sin ( x )} d x

Take the constant out:

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

= 3 \cdot \int \frac{sin ( 2 x )}{sin ( x )} d x

Rewrite using trig identities

= 3 \cdot \int 2 cos (x) d x

Take the constant out:

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

= 3 \cdot 2 \cdot \int cos (x) d x

Use the common integral:

\int cos (x) d x = sin (x)

= 3 \cdot 2 sin (x)

Simplify

= 6 sin (x)

Add a constant to the solution

= 6 sin (x) + C

\int (x^{4} - 6 x^{2} + 5) d x

\int \frac{x + 1}{x ^{2} - 2 x + 5} d x

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

\int sin (\frac{nπ}{l} x) d x

\int \frac{1}{6 6 x ^{5}} d x
