Question 773187
{{{ sqrt(x^2 + 4)}}}


{{{ sqrt((2*tan(theta))^2 + 4)}}}


{{{ sqrt(2^2*tan^2(theta) + 4)}}}


{{{ sqrt(4*tan^2(theta) + 4)}}}


{{{ sqrt(4(tan^2(theta) + 1))}}}


{{{ sqrt(4)*sqrt(tan^2(theta) + 1)}}}


{{{ 2sqrt(tan^2(theta) + 1)}}}


{{{ 2sqrt(sec^2(theta))}}}


{{{ 2*sec(theta)}}}



Answer: {{{ 2*sec(theta)}}}
