note 14885 deleted from function.sqrt by nlopess

Note Submitter: office at universalmetropolis dot com ---- as there are no given examples and i have spent all day working on mathematic functions, here is some trigonometry: Say we are looking for the hypotenuse of a right-angled triangle and know two of the lengths. $side_a = 4; $side_b = 7; // square each side, then add the total $verybignumber = ($side_a*$side_a)+($side_b*$side_b); // now we find the square root using the SQRT function $hypotenuse = sqrt($verybignumber); print $hypotenuse; voila.
