So I can do the difficult range question but do a sign error so get the coordinates of A wrong by calculating the gradient wrong and missed a solution for one of the trig equations! grrrrrrrr

Its actually increasing

How did you get it to be increasing?

K was negative and it was divided by the square of some function of x. Meaning the gradient at any point could only be negative. As it's always going to be negative/positive = negative. Meaning it's a decreasing function?

About the asymptote - http://www.wolframalpha.com/input/?i=y%3D%282e%5Ex%29-5

See the range, it should be y=-5 for f(x) and y=5 for |f(x)|

Not y=5

I genuinely think that this was a difficult paper, there was a lot in there that stretched people's knowledge and I think that will show in the grade boundaries. We're forgetting that the boundaries are set by how people have done overall, if a lot of people think they've done badly then the boundaries will reflect that.

I would agree it was trickier compared to previous years papers (except June 13 which was harder by miles). All I'm saying is that there was nothing on that paper which would have thrown a well prepared candidate off. My further maths class found it to be a reasonable paper.

What did everyone get for question 10 part a? I nearly missed the entire question because it was on the last page so I only had 5 mins to do it!

Just another copycat troll, sad really.. :h:

Well the point of the thread is for people to give their opinions about how they found the paper. We don't slack people when they say they found it really difficult, so then why do we do slack people when they find it easy?

Some people will do good, some will do bad. That's the nature of exams. A person who did good should have every right to boast about their exam as someone who did bad and complains.
