On a test on a course that isn't math, but uses it, such as physics or engineering, would using a CAS to reduce the handiwork I have to do be considered cheating? For example, what if I used the equation solver to solve equations, rather than do it by hand? Or what if I let the calculator do integrals and differentiations for me?
This is assuming the professor never said anything about what kind of calculators were allowed, nor about what we do with them. (Using them as a cheat sheet would definitely be cheating, but this is not what I am asking about.)
