[Frama-c-discuss] A problem with math functions

Yes, as far as I know, no SMT solver know about trigonometry. But there
are other provers available as Why3 back-end that do, and Why3 drivers
indeed know how to use them : MetiTarski, Coq, Isabelle/HOL

For proving floating-point programs correct w.r.t a specification
involving real numbers, it is mandatory to use provers outside the SMT
