Mathematics . the set of all points, lines, or surfaces that satisfy a given requirement.
^according to dictionary.reference.com
though i would define it as, the course of line, whose corresponding point is equidistant from a point or a set of points.

hey is an empty set an improper subset?

Don't believe CIE will only give stuff within the syllabus. In chem atp they asked the color of some salt which was not in syllabus.

i know, but they cant give Q for which students are all helpless to find any method. They always give whose Qs from out of syllabus for which candidates can at least make a wild guess.

It,s an improper subset of itelf only only otherwise it,s a proper subset of every other non-empty set

"Let A be a finite set having n elements. Then the total number of subsets of A is (2n) and the number of proper subsets of A is (2n−1)."
bus yahi yaad rakho

2 raised to power of n you mean not 2 x n

hey wait! O.O
i guess both theorems are right, coz 2^n - 2 = 2^(n-1)

wait wait
isnt it (2^n)-1 ?

i think us banday nahi kahin say ghalat parhi hai #misunderstanding
coz its the only thing contrasting with all the info sstated there.

Right, but I meant as in there are some questions in past papers regarding the given figures and they ask to describe the locus , i was confused about what to mention.

just describe 2 - 3 points which are factual foor those locii. like you describe 2-3 thing when describing transformation, just desccribe equidistant from what, what is the lucus? (circle/angle bisector/perp. bisector/parallel line), and anything else u see there.

5x/x+1 - 2/x+1 = 8
Please solve!

 

[peacce]

hey guys any tips for p1?

 

[peacce]

?!?!?!??!!?

5x/x+1 - 2/x+1 = 8

Is the answer: 13x^2-18x-1=0 ?
