Re: Finding ArcCosine
jemidiah, Your code is a lot more simple than mine but I was not sure whether the OP. was using VB6 with its arc tan function.
My method of successive converging iteration is pretty simple, but not "rocket science". However if it works and is not too slow, then it is a solution. This approach can be applied to solving a lot of functions for which the inverse calculation is not readily available. I also use it, with variations, for extrapolation between points on experimentally derived data graphs.
The degree of agreement with my scientific calculator was not bad.
Is it not time for the OP. to respond to these replies and to mark the thread as Resolved if he (she) is satisfied?
