I found programming to be exceptionally helpful when learning trig. I was able to not just understand a few examples, but really generalize the concepts and relate them.

That was an experience that really stuck with me, and I must say I'm kind of surprised at many of the naysayer opinions in this thread.

To this day I'll fire up a REPL to explore some math ideas. Maybe I'm weird and am just more programming minded than most, or my prior programming helped.
