Look ....Sequence seems to be hard but actually if u use a little bit of ur brain :p u will surely find it easy!!Believe me!!Just look at the question ....the first few parts are easy and the next part which u will find hard ...will be based on these easy parts that is a combination of those answers or there will be some relation which varies according to the question!!
Eg.if u r given a table with first four columns like n=1 ....to ....n=4 and then u wil have a column for n
this table will have info abt three sequences and u will have to find the nth term!!now the first two will be simple one ...like some addition or multiplication which u can do by the rules or formulas u have...however for finding the third one u will have a problem...but if u look carefully u will find that there may be some relation with the first two sequences...may be multiplying the first two gives the third one or adding them may give the third one ...so what ever it is u will find nth term in the same way like suppose the first two are multiplied togethr to give the third one so to find the nth term for the third one u multiply the nth terms of the first two!!That simple.... :)
So this was smthng complicated ...other type is usually nt that hard!!If stuck at any question...i'll be glad to help...so plz don't hesitate!!
Hope this helps !!
Jazak ALlah Khair!!

Re: IGCSE Maths Tips nov.2010!Confused!have questions?Post h

ok so i will tell u abt Q:4...tell me if u need Q:6 as well
now in this since it is a square and since RC=BQ...angle BQP and CRQ shud also be the same....and angles of the square is ofcourse 90 (RCQ and PBQ)
therefore the third angle of both triangles are sam and hence the sides PB and QC are same....actually i didnt solve this ...i am just explaining....if u have doubt or if there's any contradiction with the mark scheme let me know but i think u'll work out the way stated....i'll be really sorry for any mistake from my side :)
Hope this helps!!
