which rank wil b considered at counselling time AIR OR STATE RANK.IS THERE ANY QUOTA FOR LOCAL STUDENTS IN NITS AND IIITS

The remainder when x=1! + 2! + 3! + 4!+ .....+ 100! is divided by 240 is

a)153

b)33

c)73

d)187

LETS TAKE AN EG

FIND DET OF ABOVE MATRIX

IN THIS CASE DET=0 (IF DET IS NOT EQUAL TO ZERO ITS RANK IS DECIDED AS 3)

SO FIND DET TO ALL THE SUB MATRICES OF ORDER 2X2

IF DET OF ALL THE 2X2 MATRICES =0 THEN ITS RANK IS 1 IF NOT ITS RANK IS 2

NOTE:IF DET OF EVEN ONE OF THE SUBMATRICES OF ORDER 2X2 IS NOT EQUAL TO ZERO THEN ITS RANK IS 2

aply log on bothsides2logx*logx=log1000x2(logx)^2=log1000+logx (as logab=loga+logb)2(logx)^2-logx=3 (as log1000=3)its a quadratic eqn in logxsimplify (logx+1)(2logx-3)=0==>> logx=-1 or logx=3/2==>> x=10^-1 or 10^3/2NOTE:ALL LOGS ARE TAKEN TO THE "BASE 10"

no its impossible to completely say sinx=x we just use this for solvng and simplifying the problems as sinx is a incresng function and only for small values of x

integral of x2+1\x2-1

of x2?1x2+1

what is the range of (arcsinx)^2+(arccosx)^2

if u r not able to remember derivatives like sin^2+cos^2=1
u can use the mantra SC:ST:Co Co
that means S=sin when it is with cos
S=sec when it is with tan
Co first is cosec and later is Cot

just if u want to answer any MCQ u can substitute any angle which satisfies the triangle(as it is given in the problem).u can do it easily

pi radians=180 degrees=200 grades
or
pi/2 radians=90 degrees=100 grades
my frnd use this u can solve any angle given to u. all the best

can any one say what is the value of zero(0)

thanks

how area of circle is (22/7)r2

how can sin0=0 if any angle in a rt triangle is equal to zero how triangle is formed

it is very nice and useful

very nice collection. it is really helpful

please give material on isomerism

i will be very grateful if it send to me // shiva_mothkuri@rediffmail.com
