-In mathematics and tuning, the '''root mean square''' of two frequencies <math>f_1</math> and <math>f_2</math> is equal to <math>√(\frac{f_1^{2} + f_2^{2}}{2})</math>
+In mathematics and tuning, the '''quadratic mean''' of two frequencies <math>f_1</math> and <math>f_2</math> is equal to <math>√(\frac{f_1^{2} + f_2^{2}}{2})</math>.
+== Examples ==
+The quadratic mean of [[1/1]] and [[3/2]] is √([[13/4]]).
+The quadratic mean of [[5/4]] and [[6/5]] is √(1201/800).
+The quadratic mean of [[9/8]] and [[10/9]] is √(12961/10368).
