integral of ((1+tan(x)))/(sin(2x))

\int \frac{( 1 + tan ( x ) )}{sin ( 2 x )} d x

\frac{1}{2} ln ∣ tan (x) ∣ + \frac{1}{2} tan (x) + C

Solution steps

\int \frac{1 + tan ( x )}{sin ( 2 x )} d x

Expand

\frac{1 + tan ( x )}{sin ( 2 x )} : \frac{1}{sin ( 2 x )} + \frac{tan ( x )}{sin ( 2 x )}

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int \frac{1}{sin ( 2 x )} d x = \frac{1}{2} ln ∣ tan (x) ∣

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

= \frac{1}{2} ln ∣ tan (x) ∣ + \frac{1}{2} tan (x)

Add a constant to the solution

= \frac{1}{2} ln ∣ tan (x) ∣ + \frac{1}{2} tan (x) + C

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

\int \frac{14 x + 9}{( 2 x + 1 ) ^{2}} d x

\int 12 x e^{x} d x

\int \frac{x ^{2} + 19 x + 10}{2 x ^{4} + 5 x ^{3}} d x

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