Dear students, congratulations on such excellent results in the Leaving Cert. This year more than 37% of all Coláiste Bríde students have succeeded in being awarded the 25 bonus points in maths nearly 50% better than the national average! It is testament to the hard work, ambition and courage of your class. This morning as the CAO offers come out my best wishes are with you all. Go n-éirí an t-ádh libh. Mr R

The melting snowball 2014 Sample P1 Q9 b

6/2/2014

0 Comments

 
Comment: Though this problem is one of only two examples given relating to strand 5 of Project Maths. The solution to this problem requires the use of Differentiation Methods (either parametric or implicit) that are no longer on the LCHL Course! 
However, since this question was in the 2014 Sample Paper it is important. Here is a similar question about an increasing sand pile from Roantree's notes. If you understand this you should be OK.
