1@sushrut hey i m really sorry that happened by mistake .i ve edited ma post n sorry again
13The sum of all the coefficients of the expansion (x+y)^n is 1024 then the greatest coefficient occurs in the r th terms where r is equal to
1.. 6
2.. 5
3.. 4
4.. NONE
13The last 1 for this thread
Assume R and S are (non-empty) relations in a set A. Which of the following relation given below is false
1. If R and S are transitive, then P U S is not transitive
2. If R ans S are transitive, then R U S is symmetric
11 6 is ans
fr tht convention the reason for more hotness above is convection only .conduction do not explain this phenomena
13@richa yep ...u r ryt abt both of them ...acc to the ans given
post 38 ......i noe its the 6th term but for that is for r =5 ryt thts wat they r askin
can u plz...xplain the last ques ...i mean the solution
1i just took two sets r=[(1,2)(2,3)(1,3)] s={(a,b)(b,c)(c,a)}rus is transitive
nd u can also think tht all elements of r ,s ll be elements of rus n thus no element ll exists in therus which is non transitive
13antisymmetric ....i dunno ...is it in our course ....havnt heard of it
@~~~~~ no its the second option
i m quite confused b/w 1 nd 2 .......cele plzz. .....ans if u r there
1P.S. : hey deepanshu... dun post questions lyk dis dude... it's very difficult to search for them... either post all the questions in d first post itself (by editing it for every question) or start a new forum for each question... aise post karne se questions solve karne ka interest bhi chala jayega... try to understand... :)
13even i thot so .....fter i did tht .....ppl hav ignored sum ques....
the vry 1st ques remains unanswered ......
wud sum1 lyk to ans tht
13no maniboy.....
even i thot tht
but the ans given is the other option
13yeah even i thot so but as olwz wat i thot wsnt the ans.....
the ans tht is given(not reliable at ol) is 3.
sum1 ....plz verify this
13Which of the followin the reaction is iuniomolecular
