Question
**Topic: Analyzing Scalar and Vector Fields**

**Instructions:**
Let \( f \) be a scalar field and \( \mathbf{F} \) a vector field. State whether each expression is meaningful. If so, state whether it is a scalar field or a vector field.

**Questions:**

(a) \(\text{curl}(f)\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(b) \(\text{grad}(f)\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(c) \(\text{div}(\mathbf{F})\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(d) \(\text{curl}(\text{grad}(f))\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(e) \(\text{grad}(\mathbf{F})\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(f) \(\text{grad}(\text{div}(\mathbf{F}))\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(g) \(\text{div}(\text{grad}(f))\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(h) \(\text{grad}(\text{div}(f))\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(i) \(\text{curl}(\text{curl}(\mathbf{F}))\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(j) \(\text{div}(\text{div}(\mathbf{F}))\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(k) \((\text{grad}(f)) \times (\text{div}(\mathbf{F}))\)  
- [ ] scalar field  
- [ ] vector field  
- [ ] not meaningful  

(l) \(\text{div}(\text{curl}(\text{grad}(f)))\)  
- [ ] scalar field
