integral of (sec(sqrt(x)))/(sqrt(x))

\int \frac{sec ( x )}{x} d x

2 ln tan (x) + sec (x) + C

Solution steps

\int \frac{sec ( x )}{x} d x

Apply u-substitution

: \int 2 sec (u) d u

= \int 2 sec (u) d u

Take the constant out:

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

= 2 \cdot \int sec (u) d u

Use the common integral:

\int sec (u) d u = ln ∣ tan (u) + sec (u) ∣

= 2 ln ∣ tan (u) + sec (u) ∣

Substitute back

u = x

= 2 ln tan (x) + sec (x)

Add a constant to the solution

= 2 ln tan (x) + sec (x) + C

y^{^{''}} - 2 y^{^{'}} - 3 y = - 3 t e^{- t}

x \to 1 lim (x - 2)

x \to \infty lim (\frac{2 ^{x + 1}}{3 ^{x - 1}})

\int x^{2} sin (4 x) d x

(x^{5} - 9) x
