Hello, I am a java developper and I noticed, looking into the API, that there are quite a few trigonometric functions available to the developper either in sql or in java. I assume that these functions are used by some of us, otherwise they would not be there in the first place. I am just curious to know how are they used in the field of finance? Can someone please provide practical examples of uses of the sin, tan, cos functions? Thanks in advance, Julien Martin.
Why do you assume they are used in the field of finance? Trigonometric functions are most likely to be used by applied mathematicians, physicists, engineers etc.
I would think that few, if any, plain finance applications would use them; such applications tend primarily to do ordinary arithmetic (lots of it). I would think they might be used in some macro-economic models, but I am no expert and couldn't say where.
Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.
