Enter a number in any field and the other 3 results will be calculated to solve the golden ratio. Use a GET statement to come into this page with A, B or A+B already set. For example, http://www.calculatorsoup.com/calculators/math/goldenratio.php?A=45 will set A=45 and calculate the rest. Further, to set A, B or A+B, say to 45, append the URL with "?A=45" or "?B=45" or "?AB=45" WITHOUT THE QUOTES.
The golden ratio, also known as the golden mean, is the value q where q = (A+B)/A = A/B.
For this calculator we use q = ( 1 + sqrt(5)) / 2, which is rounded to 1.6180339887499. We then round the final answers for A and B to whole numbers. An exact value for q can be researched at MathWorld for Golden Ratio.
