I wouldn't call it laziness, I would say it is good style. It allows you 
to easily change the code later for different parameters, and there 
isn't any reason not to use an available function for it's intended 
purpose.
Oh, and in MegaPOV, "sqrt(0.75^2 + 0.5^2)" would work just fine(the ^ 
operator has been added), and you could use "sqrt(pow(0.75, 2) + 
pow(0.5, 2))" in official POV.
