| Jun 9, 2012 at 11:02 | comment | added | Artes | I mean programming behind transcendental mathematics deserves to be distinguished among the rest of the world. Yes, I'll start soon (as soon as find a bit of time) this thread on meta. | |
| Jun 9, 2012 at 10:44 | comment | added | J. M.'s missing motivation♦ | Not terribly convinced, @Artes. The watershed is "algebraics" and "everything else", yes? By convention we have elected to use the term "transcendental" for "everything else"; i.e., it's not a special case, and I don't see the need for a distinction for things that aren't a special case. If you want to argue further, maybe you should start a meta thread and see what other people say... | |

@J.M. We have the polynomials tag, mathematics behind solving transcendental equations is really a step forward, e.g. see blog.wolfram.com/2008/12/18/…

| Jun 9, 2012 at 10:15 | comment | added | J. M.'s missing motivation♦ | In general, @Artes. An example off the top of my head: a solution to a question tagged equation-solving would either be general or be specialized to algebraic cases, and we don't have an algebraic tag, do we? | |
| Jun 9, 2012 at 10:12 | comment | added | Artes | @J.M. Did you mean the point of a transcendental tag to this question or in general ? I could point out right now about 5 questions (this one among them) which should be tagged with that. | |
| Jun 9, 2012 at 10:06 | comment | added | J. M.'s missing motivation♦ | @Artes: I don't quite see the point of a transcendental tag just yet... | |

I think here should be added a tag special-functions and a new one transcendental since we have in the question e.g. Sin[Sin[x]]. There were 6 editors of the OP so I wouldn't like to be another one.

You can accept ONLY ONE of the answers (clicking the green tick beside an answer), which you find the most helpful. You can upvote EVERY answer you find helpful or downvote if you find an answer misleading. | |

A tiny comment on Reduce[]-based methods: all of these hinge on the fact that Reduce[] apparently knows quite a fair bit about the transcendental functions built within Mathematica. If, however, you are dealing with a black-box function that can only evaluate at numerical values (you can simulate this behavior with something like f[x_?NumericQ] := Haversine[Pi x]), then Reduce[] won't be able to do much.

You might be interested in this question. Anyway, for finding the roots of a function of a single variable, you can directly use the output of Plot[] to find initial approximations for FindRoot[]. If you're interested in that approach, I can write up an answer.
