Solving a trigonometric equation - wrong results? - Сообщения

Dear all,
I try to solve a simple trigonometric equation with "solve", but I don't find results in some situation and I don't understand why.
Any help is appreciated.
Thank to all

Three things here:
1. All maths fncts are Padé rational fraction.
on small range of the argument, then processed for extending.
21 floating 18 considered trues conserved 15 [standard tables].
2. '0' is undefined generally.
3. 5*π doctored
solve bloc is not fool proof all/any applications

Dear Jean,
thank you for the answers.
To be sure if I understand right: the mistakes are from the approximation of the functions.
I apoligize, but I don't understand your "sanity check". Could you explain a little bit?
Thank you

Often, in advanced works, we have to check [sanity check]
results. Casio [Keisan] on line calculator(sss..] is Bible.
As the matter example was Bessel: here is the document.
Link to Bessel-Keisan in turquoise.
Cheers ... Jean.
