-### Real Analysis Proof Guidelines  
-For Real Analysis proofs, follow these principles to ensure clarity, rigor, and logical completeness:  
-
 a. **Justify Every Step**  
    - Provide detailed reasoning for each step and explicitly justify every bounding argument, inequality, or limit claim.  
    - If concluding that terms vanish in a limit, clearly explain why.

    - If proving continuity or differentiability, check symmetry in approach from both sides (left-hand and right-hand limits or derivatives).  
 
 c. **Function Definitions and Explicit Statements**  
-   - When proving continuity, explicitly confirm that \( f(x) \) is **defined** at the point of interest and state what its value is.  
+   - When proving continuity, explicitly confirm that f(x) is **defined** at the point of interest and state what its value is.  
    - If a function is given piecewise, clearly state the function values at transition points before evaluating limits.  
 
 d. **Limit Justifications and Transitions**  
-   - When using standard limits such as \( \lim_{t \to 0} \frac{\sin(t)}{t} = 1 \), briefly justify why it applies (e.g., from Taylor series, L'Hôpital’s Rule, or first principles).  
-   - If a limit is computed informally before a formal \(\epsilon\)-\(\delta\) proof, explicitly state that the formal proof serves to confirm the computed limit rigorously.

+   - If a limit is computed informally before a formal epsilon-delta proof, explicitly state that the formal proof serves to confirm the computed limit rigorously.  
    - Ensure smooth logical transitions between different parts of the proof by briefly explaining why one step leads naturally to the next.  
 
 e. **Function Properties and Integrability**  
    - If stating that a function is Riemann integrable, compact, or uniformly continuous, explain why.  
-   - If claiming a function is continuous for all \( x \neq 0 \), explicitly justify why using function composition, bounded functions, or known theorems.  
+   - If claiming a function is continuous for all x not equal to zero, explicitly justify why using function composition, bounded functions, or known theorems.  
    - When assuming an integral is finite, provide justification based on function class properties (e.g., Riemann integrability implies boundedness).

+   - When proving uniform convergence, ensure that the bound obtained is independent of x to establish uniform control.
