fudgester SG In some situations, it would be a lot easier to express angles in radians. And in fact, the SI unit for angle is in fact the radian: http://en.wikipedia.org/wiki/SI_derived_unit
dark_snowboy SG you taking Os this year? every night Before sleep, memorize that you need to change your mode of your calculator
MooKu SG Oh no. Does that mean you did everything correctly but the answers were all wrong because your calculator was feeling rad and you only realized it at the end of the examination??
ndmmxiaomayi SG Must be E Maths. Because I always forget to switch whenever I do A Maths and E Maths. Got fed up, buy 2 calculators.
