Why do business calculators have log/exp but not basic trig functions?

[Carsen]

I don't really know why Pier4r. As an accounting student, I haven't run across the need for trig yet. However, I would still like these functions built-in on a 12C for those special cases of me tackling some calculus on my free time and other uses.

Although we can all come to the conclusion that the 12C's functionality won't change because it continues to sell. Plus, any changes would affect it's acceptance on some exams.
