hey i dunno about solns but how much u r expecting in each subject temme

This is a thread on assertion and reasoning questio. Please add more . it will be really helpful Generally we make a lot of silly mistakes in this ectionit'll help . 1.(y' )^2 + xy' - y=0 y(2)=-1A: The Area bounded by the axis and soln . is 2/3.R: It has a singular solution

hey howd you get that formula

Words cnt fill the void of acivity

Fight now Fight Hard

Do not think much of other things only studies

Study till the hour you think is enough then go to sleep

do not join any course sit at home study 12 hrs a day

The answers , i dont think you need a solution if you do just ask ..

1.d

2,b

comp.

1.b

2.a , eventhough i'm getting coonsidering no gravity on setup v(transverse)=sqrt(2pi)*wr just a guess if any is getting this correctly plz tell

3.b

why is integral of log(tanx) over 0 to pi/2 zero when it definite integral gives area under curve

the locus is x^2*c^2+2cxy-y^2c^2-2cx^3-2y^2x^2

where is 0,0 is given point and x=c is the given line

I think the answer is Pair of straight lines coz the| abc.....| determinant turns out to be 0.

are you sure ???

Coz doesnt definite integral gives area under curve here we have logtanx tanx-->inf. to pi/2 the are i can t think can be zero .

IIT BOMBAY OLYMPIAD QUESTION INTEGRATION SOLVE THIS !!integral-((pi/2)(0)[log(tanx)])

is there not ISC student here ?

ISC MATHEMATICS Please gimme correct answers for all probabibility ques. on probability in ISC maths exam .

Please solve this problem .

Probability - Very important problem urgent solution required

if (x,y) is a subset of (1,2,3,4......,100)

Find probability such that ---xy---- is a multiple of three.

How did you get x=sqrt(l) for Wmax. ?

That is again wrong . By the way i think the answer is x=l .

For Work = Area under Fx graph and hence here F being a parabola , o and l being roots 0 --> x--> l

gives Wmax

Mishra ,

I think your solution is wrong

F is a variable

you cannot consider W=F.x .

It has to be W=integralof(Fdx)

So both your ans your soln . is wrong

Please come up with a correct answer

CONCEPTUAL SHM :F=kx(x-l) 0<=x<=lFind compression for max work done with reason

I study in ISC Board non delhi how can i get into DCE

I am living in jamshedpur can i sit for the cee 2009
