integral of (sin(2t))/(sin(t))

\int \frac{sin ( 2 t )}{sin ( t )} d t

2 sin (t) + C

Solution steps

\int \frac{sin ( 2 t )}{sin ( t )} d t

Rewrite using trig identities

= \int 2 cos (t) d t

Take the constant out:

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

= 2 \cdot \int cos (t) d t

Use the common integral:

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

= 2 sin (t)

Add a constant to the solution

= 2 sin (t) + C

\int 2 cos (x) - 9 sin (x) d x

\int \frac{4}{x 16 - ln ( x ^{2} )} d x

\int 3 x^{\frac{4}{3}} d x

\int x + \frac{2}{x} d x

\int \frac{3 x ^{4} - 9 x ^{2} + 1}{x ^{2}} d x
