    Mathematics: Post your doubts here!

    Another question! By any chance do you guys happen to remember the value of K in the question related to functions in Paper 12? Please tell me it was -3. It was the same question in which they asked to find the inverse for the function. This'll probably help if you can't quite remember the...

    Thresholds for paper 12 maybe like 56 or 57 but I really don't think threshold for 42 will drop that low. Will be around 44-45 by my guess!

    Mathematics: Post your doubts here!

    Well, I do have another question, kind of a complex one. During P1 I actually kind of wasted the space given originally, however I think I did come up with the right solution on an extra sheet that I borrowed. Anyways, I didn't mark my solution number on the sheet I took even though I think it...

    Till where my knowledge lies that statement (the one with slipping up and down ) changes the question as in that case we would only have changed the direction of the friction, but here since the direction of P wasn't specified, I think we were expected to change the direction of P. What do you say?

    I seriously don't know what did. I can explain you the way I did it though. I solved the problem by simply taking the direction of P acting up the line of greatest slope for 1 case and down the slope for the other one. Also changed the directions of friction. Made 2 simultaneous equations...

    Okay fellas! Now I know this question has already been answered but I really need opinions of more than just 1 person. My value for mew was about 5.2. How much marks am I really expected to lose here. The question was worth 7 marks just so you know.
