Had a quick question, in FP2 June 2015, how do you know the answer to 1b? The answer is apparently x>1 however I dont understand how we're just meant to see that since it is a 1 mark question.
Is the TI-83 plus calculator permitted for this exam or not? Doesn't matter too much if it isn't - I'm just slightly concerned about plotting polar graphs at the moment.

i'm pretty sure you can use it, it doesn't have algebraic integration/differentiation does it?
pi+arctan(0.5)Ok so these are two possible values.Do I essentially draw two half lines?
Essentially yes, but if you think about it adding pi rotates it to the other side, so youre drawing two half lines that start from the same point and go in opposite directions, aka a full line
On a shading question like where you shade the region for which say | Z | < x which has been transformed can you use a pencil to change the equal signs to inequality signs on part b and then state in part c refer to pencil inequalities or something?
