 | | Re: evaluate inverse cosine, sine in IC —Gary Livick
|
| | | I've been trying to do this as well. The problem I have found is that the Taylor series expansion needs to be developed near the solution to get accurate results. Some may wonder why finding the arcsine of a number might be of interest. If one has a (...) (25 years ago, 29-Nov-99, to lugnet.robotics.handyboard)

| | | | Taylor series should converge quite rapidly. After 2 or 3 terms, the error is usually neglectable (depending or your demands, of course: this should be fine for up to a few decimals) For those not familiar with the Taylor expansion, I've added a (...)

| | | | Another technique for finding trig functions and their inverses used by both HP and TI in their calculators is the CORDIC algrorithm. A description of the technique with lots of references can be found at: (...) (25 years ago, 29-Nov-99, to lugnet.robotics.handyboard)
