Can past students give some tips on how to minimise mistakes in Graphs & Relations?
I find it quite straightforward, but it is easy to slip up in linear programming (especially when writing the constraints). Any suggestions to address this issue?
Well, I don't know how effective this will be for you, but whenever the question provided information in worded form and asked us to create a constraint, I would check my answer by substituting random values to make sure that the constraint was right.
eg. 2012 Exam 1: Graphs and Relations q 8
at least 5 loves of white bread will be made for ever loaf of brown bread that is made w= white bread made per day
b= brown bread made per day
I'd first write up my constrain: w ≥ 5b
I'd then check this by subbing in random values for b. So, if I made 1 brown bread, I'd made 5 white bread. If this matches the constraint they provided originally in words, you'd know you have the right answer.
Hope that makes sense.
