integral of 1/2 sec(v)tan(v)

\int \frac{1}{2} sec (v) tan (v) d v

\frac{1}{2} sec (v) + C

Solution steps

\int \frac{1}{2} sec (v) tan (v) d v

Take the constant out:

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

= \frac{1}{2} \cdot \int sec (v) tan (v) d v

Apply u-substitution

: \int 1 d u

= \frac{1}{2} \cdot \int 1 d u

Integral of a constant:

\int a d x = a x

= \frac{1}{2} \cdot 1 \cdot u

Substitute back

u = sec (v)

= \frac{1}{2} \cdot 1 \cdot sec (v)

Simplify

= \frac{1}{2} sec (v)

Add a constant to the solution

= \frac{1}{2} sec (v) + C

\int cos (2 x) e^{- s x} d x

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

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

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

\int \frac{4 x - 5}{2 x ^{3} - 5 x ^{2} - 3 x} d x
