English term or phrase:usage of "is"
There is a figure in the text, a frequency (f) vs. wave number (z) plot. In the caption of the figure the wave number is expressed in terms of other quantities. Which of the following sentences is correct?
a) The wave number z = a q / 2 pi.
b) The wave number is z = a q / 2 pi.
Is a) correct, since the sentence can be read as "The wave number z is equal to "a" times "q" over "2 pi"?", or is b) correct/better?
This sentence appears in the caption, which contains a longer explanation.
