If tan2(x) = 1/4 then tan(x) = ±1/2 so x = tan-1(±1/2)

Use atan on the calculator on the home page here to find the values of x (atan is the same as tan-1).  This will give you angles in the first and fourth quadrants, but there will also be solutions in the second and third quadrants (obtained by 180° ± x).
