Answer 3

ok is it related to vector analysis

Answer 4

yup
but i m so weak in maths

Answer 5

i have problem with two questions
and another is

if the roots of the equation (a2+b2)x2-2(ac+bd)x+(c2+d2)=0 are equal, prove that a/b=c/d

Answer 6

can u give me solution

Answer 7

i will give you for the second ques in few minutes but i don't know about integration of above one

Answer 8

i also dont know
becoz i m also from commerce stream

Answer 9

you also may email me at devil.magra@yahoo.com

Answer 10

i am writing solution of Q2 asked by u

Answer 11

ok

Answer 12

first we apply quadrattic formula

Answer 13

ok

Answer 14

mr. sumbul can u email me solutions of both questions at devil.magra@yahoo.com
becoz of i will loss my train

Answer 15

hey i got one answer
if two roots are equal, b2-4ac=0, or (-2(ac+bd))^2 - 4 (a^2 + b^2) (c^2+d^2) = 0 or 4(ac)^2 + 8abcd + 4(bd)^2 - 4(ac)^2 - 4(ad)^2 - 4(bc)^2 - 4(bd)^2 = 0 or 8abcd -4(ad)^2 -4(bc)^2 = 0 or (ad)^2 - 2(ad)(bc) + (bc)^2 = 0 or (ad - bc)^2 = 0 or ad - bc = 0 or ad = bc therefore, a/b = c/d

Answer 16

yes it is correct i was also typing it

Answer 17

do u still need solution?

Answer 18

yes please mail the solution of
find the are of circle x2+y2=a2 by integration

Answer 19

ok bye
thanks
i give u first ur reward
