Hi all,

another integral problem, I thought this could be done to calculate the simple:

\int\_{-2}^{2} |x| \ dx

with this code:

```julia

x = symbols("x")

f(x) = abs(x)
integrate(f, (x, -2, 2))

```

The errors:

**LoadError: MethodError: no method matching integrate(::typeof(f), ::Tuple{Sym, Int64, Int64})**  
**Closest candidates are:**  
\*\* integrate(::Function) at ~/.julia/packages/SymPy/7cg6m/src/mathfuns.jl:80\*\*  
\*\* integrate(::Function, ::Number, ::Number) at ~/.julia/packages/SymPy/7cg6m/src/mathfuns.jl:76\*\*  
\*\* integrate(::SymPy.SymbolicObject, ::Any…; kwargs…) at ~/.julia/packages/SymPy/7cg6m/src/importexport.jl:102\*\*
