WebYes, square roots can create 2 answers -- the positive (principal) root and the negative root. When you are working with square roots in an expression, you need to know which value you are expected to use. The default is the principal root. We only use the negative root when there is a minus in front of the radical. For example: 8 + sqrt (9) = 11 WebRMS roughness and waviness: The root mean square (RMS) method is the most common way optically-smooth surfaces are specified in the United States, while in Europe it is more common to specify absolute roughness. The RMS average of profile height deviations from the mean line is utilized to statistically analyze the smoothness of an optical surface.
