Integral(1/sqrt(x^2 + 4), (x, 0, 1))

Detail solution

TrigSubstitutionRule(theta=_theta, func=2*tan(_theta), rewritten=sec(_theta), substep=RewriteRule(rewritten=(tan(_theta)*sec(_theta) + sec(_theta)**2)/(tan(_theta) + sec(_theta)), substep=AlternativeRule(alternatives=[URule(u_var=_u, u_func=tan(_theta) + sec(_theta), constant=1, substep=ReciprocalRule(func=_u, context=1/_u, symbol=_u), context=(tan(_theta)*sec(_theta) + sec(_theta)**2)/(tan(_theta) + sec(_theta)), symbol=_theta)], context=(tan(_theta)*sec(_theta) + sec(_theta)**2)/(tan(_theta) + sec(_theta)), symbol=_theta), context=sec(_theta), symbol=_theta), restriction=True, context=1/sqrt(x**2 + 4), symbol=x)

Now simplify:

$\log{\left(\frac{x}{2} + \frac{\sqrt{x^{2} + 4}}{2} \right)}$
Add the constant of integration:

$\log{\left(\frac{x}{2} + \frac{\sqrt{x^{2} + 4}}{2} \right)}+ \mathrm{constant}$

The answer is:

$\log{\left(\frac{x}{2} + \frac{\sqrt{x^{2} + 4}}{2} \right)}+ \mathrm{constant}$
