The equation is .

Compare the equation to .

Than A = 1, B = 4, C = 4, D = 0, E = , F = 5.

Rotate the axis and angle to the equation .

         (Substitute A = 1, B = 4, C = 4)

Now using the half angle formulas in the form

Substitute in .

         (Take out common term )

Substitute in .

Using the formulas .

               (Take out common term 5)

                 (Using the formula )
