## Tactic nlsat
### Short Description
(try to) solve goal using a nonlinear arithmetic solver
### Example
```z3
(declare-const x Real)
(declare-const y Real)
(assert (> (* x x) (* y x)))
(assert (> x 0))
(assert (< y 1))
(apply (then simplify purify-arith nlsat))

Tactic Documentation:
## Tactic qfnra-nlsat
### Short Description
Self-contained tactic that attempts to solve goal using a nonlinear arithmetic solver.
It first applies tactics, such as `purify-arith` to convert the goal into a format
where the `nlsat` tactic applies.
### Example
```z3
(declare-const x Real)
(declare-const y Real)
(assert (> (* x x) (* y x)))
(assert (> x 0))
(assert (< y 1))
(apply qfnra-nlsat)
```
