    No for indices I know they r coz we don't want to clutter up .khair I uess it,s more of a credit to write in inverse powers and tht like,contrary to a denominator khair the final answer shud be in simplified form..Tht,s the understatement\ I am going to go with Danial..Pretty simple the time 1125

    In locus where they usually ask for 2 or more conditions,shud we draw a dotted/dashed line when for instance they ask us to shade the region of the point less or more than 5 cm from any pt..I mean do we draw a dotted arc coz dotted indicztes not part of and the boundary(arc line) is not included...

    No...read the er and u will get the idea...For scale a simple div of 2 per block is enough ...Plus it is advised to not draw more of the polygon than req coz ...look at er. Abt my query..Do we have to constr perp bisector by compasses and also SHOW arcs or we can simply do it using protractor...

    Don't take on this metod;i assume u wud be memorizing where to put 100 over the value and vice cersa Just take it like this: If they say selling price=12 percentage prf =20% CP=X so X+20%X=12 X+0.2X=12 1.2X=12(u get the rest) Conversely if they say tht 20 % profit leads to a sale price CP=120...

    Yes here we use mid but in cumulative curves they don't give in the form t<x<v they simply give in form x<=t so we simply plot tht x point in our curve plot point "t" .Nothing to it

    Also if we have qualms abt writing an answer in d.p or leaving it as fraction,how many sig fig or d.p shud we write in our answer if we consider the latter option 2 or 3?

    Wait what? The pt has to be plotted at the right frequency tht is 2 and at the mid pt of 16 and 20 i.e 18 and then we cud further join it t 20 on axis but the further part is ignored by the examiner ..Read it in MS of 2008 ppr so the Graph of Zain rocks is right in the premise of its req tht is...

    For locus questions Do we have to indicate on our diagrams tht whether this locus refers to locus given as 1(in exams) or 2(as also given in questions).I mean do we have to give a mark or arrow and write tht this specific locus is in response to the 1st condition or 2nd e.t.c
