Using ModelingToolkit I created and simplified a system of equations. If I try to print it I get:

```julia
julia> sys
Model sys with 2 equations
States (2):
  ω(t)
  ωˍt(t)
Parameters (4):
  J
  R
  A
  ρ
Incidence matrix:2×3 SparseArrays.SparseMatrixCSC{Num, Int64} with 4 stored entries:
 ⋅ × ×
 × ⋅ ×

```

How can I print the two equations in a human readable form?
