Calculation
As discussed, the golden ratio is a ratio such that
We can solve this equation to find an explicit quantity for the ratio.
We set the ratio equal to a certain quantity given by r.
Then we can solve for the ratio numerically.
We can see from the above result that the golden ratio can also be described as a ratio such that in order to get the square of the ratio, you add one to the ratio.
We can then apply the quadratic formula to solve for the roots of the equation.
The positive root is then the golden ratio.
