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

I am not an expert of business functions but are they so complicated?

Example.
Instead of a 12C with a program with trig functions, a 15C with a program and business functions?

It depends... if you only need certain functions and don't want to learn how to program, you buy the correct device and get instantly productive after a few hours with the manual. It's really a "right tool for the job" situation. The user's interface of the 12C is practically perfect for TVM calculations, everything else would be less than optimal. You can assign functions to any keys in the 41C, 42S, etc... true that, but why buy a spaceship if you are only going to use it to get the groceries?
