I see you have uploaded a mathematics exam paper containing multiple-choice questions on various topics. How can I assist you with this document? For example, I could solve specific questions, explain concepts, or verify answers. Let me know!

Here are five tasks I could help with:

1. Solve the question about convexity of functions (Q1).
2. Expand or simplify the Taylor series (Q2, Q3, or Q4).
3. Evaluate limits (e.g., Q5 or Q6).
4. Solve integrals (e.g., Q7 or Q8).
5. Discuss properties of matrices (Q15 or Q16).

Tip: For a clear understanding, tackle one problem at a time. Let me know where to start!
