But is it cos x, cos(x), cos[x], math.cos(x), or \cos x? Calculators are usually simple enough that all the ops can be buttons. So why not do it? There's always alternatives like Python, Mathematica, Maxima, Fricas, etc. which don't really bother with the buttons, because if they did, it'd look like a Chinese typewriter.

Sqrt or square root and pow aren't terms that commonly used in calculator for other languages, at least my country. And I guess sqrt shortform isn't that common used either. Able to see symbols can clear those ambiguity
