well thanks finally u helped me n i cud do d sum nicely hey u had answered my area problem.. but i had posted anoder reply.. did u check it ? could you please check it and help me out ? area by definite integrals..
well thanks bob ! seriously u made me relieved.. my friend told that 0.55 would be the answer because it states ' common tastes ' ... she told that common implies somewhere near half.. did she have a point ?
hi bob..
thanks a tonne for your useful help..
m facing problem in just one thing. and that's drawing this given graph.. how do i do that ? please help me?
well, the first pair has 0.55, second one has 0.73, and third one has 0.05..
today i had a test. i got the same in it..n i judged 0.73 as the correct answer.. but is that correct ?
hey, thanks
PLEASE HELP ME ON THIS QUESTION. I have no idea what it means to ask and how to draw the curve mentioned in it. If anyone could throw some light on the concept behind this problem, especially the second part, it would be great.
Find the area A bounded by the X-axis, part of the curve y = 1 - (8/x^2) and the ordinate x = 4 and x = 8. If the straight line passing through the point (a,k) and parallel to the Y-axis divides the area A into two parts in the ratio 4:5, find the value of a .
Appreciate your efforts. Thanks.
I came across this sum :
I have been given the rankings of ten contestants in a beauty contest.. rankings are done by 3 judges.. and their decisional rankings have been given in three columns.. So the rankings have already been given..
They have told this : " Use rank correlation to discuss which pair of judges has the nearest approach to common tastes in beauty
What i did is i paired the 3 judges, so i had 3 pairs.. then i found out the rank correlations for respective pairs.. but m doubtful for the final judgement that we have been asked to make. HOW TO DO THAT ? can anyone help ?
thanks...
i never did limits in 11th grade, but ive done sums from l hospital.. m not familiar with the formulas used in limits.. and because of the power in his sum i think no formula would come in handy.. could anyone please help me through this sum ?
lim of x tends to 0 [ sinx/x ] ^ (1/x^2).
Thanks...
hi..thanks a lot could u tell me how do i enable the option of getting notified by email on replies like yours ?
Here are some problems I couldn't get through even though I may have done some of them many days back.. Could anyone please help in any of them?
1. Int of (e^x - 1)/(e^x + 1) dx
2. Int ( cox + xsinx ) / x ( x + cosx ) dx
3. Int 1 / x^2 * root of ( 1 - x^2 ) dx
4. Int of ( 1 + sinx ) / sinx ( 1- cosx ) dx
5. Int of 1 / root of ( x + ! ) + root of ( x - 1 ) dx
6. Int of ( 2x + 3 ) /( 3x - 4 ) dx
7. Int of 1/ ( 1 + e ^ x/2 ) dx
8. Int of root of ( x / a - x ) dx
9. Int of ( x - a )/ ( x + a ) dx
10. Int of ( x^2 + 1 ) / { ( x^2 - 1 ) ^ 2 } dx
11. Int of ( 2x - 5 ) * root of ( 2x + 1 ) dx
12. Int of ( x / a + bx ) dx
13. Int of 1 / x * root of ( x^2 - a^2 ) dx
14. Int of ( 2x^2 + 1 ) * sin ^ 2 ( 2x^3 + 3x ) dx
THANKS.
