I do not agree that. For example, when b is very small (or b=0), one of the solution is in the vicinity of pi/a (or at pi/a).

It is more clear now. Firstly, there always has one solution x=0. Secondly, when |a|>|b|, there are more than one solutions than just x=0. I tried the N-R method. The problem is how to find the good initial value of x, because it stops at x=0 frequently. As mentioned by "Unplebeian", the N-R...

You are right, it can not help us find the solution.

difference Thanks! Can I get the solution by using the difference of the equation as acos(ax)=-b when |a|>|b|?

What numerical techniques can be used to get the solution or solutions of the equation ? Could you please give me a example ? Thanks a lot!

! thank you very much!
