integral of (7sin(2x))/(sin(x))

\int \frac{7 sin ( 2 x )}{sin ( x )} d x

14 sin (x) + C

Solution steps

\int \frac{7 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

= 7 \cdot \int \frac{sin ( 2 x )}{sin ( x )} d x

Rewrite using trig identities

= 7 \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

= 7 \cdot 2 \cdot \int cos (x) d x

Use the common integral:

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

= 7 \cdot 2 sin (x)

Simplify

= 14 sin (x)

Add a constant to the solution

= 14 sin (x) + C

\frac{d y}{d t} = \frac{3}{t} y + t^{5}

x \to 8 lim (- 6 x)

\frac{\partial}{\partial x} (- \frac{x}{2 x ^{2} + y ^{2}})

\int \frac{- 2 x - 1}{( x ^{2} + x + 1 ) ^{6}} d x

\frac{d y}{d x} = \frac{y ^{2}}{x ^{2}}
