Question 09 (b)  

The function satisfies and . The spreadsheet below will be used to approximate using Euler’s method. An arrow indicates that the entry of a cell will be copied down the column.
(b) Which cell will contain the approximation of ? 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

The cell is next to 3.5 in column B. 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies. We know that the cell C2 contains the approximation of , C3 contains and so on. Therefore, the approximation of is contained in the fifth cell below C2, that is, the cell C7. Answer: .
