i did through that way only. And i got the same midpoint of AC.
And through 2 point formula, i got that equation(the one I have qritten in#1)

#29 Re: Help Me ! » equation of median. » 2010-10-28 00:06:12

yes, I solved it.

But you said that my answer is not right. Is it so?
I did not understand how you got your answer

#30 Re: Help Me ! » equation of median. » 2010-10-27 20:30:07

I did not draw it like that.
Just imagined it to cut the midpoint of AC. , and solved through analytical geometry

They have asked to find a equation of median through B?

Find the equation of the median of triangle ABC through B if A= (2,4) B= (2,-3) C= (-4,-2) are the vertices.

I tried answering it and got the equation as 2x-3y=8=0 .

Is this the right answer?

Hi soha,

That answer is wrong:

5.227 * 10^3 = 5227 the correct answer is 522.7. Have you copied the problem right?

yes , the answer is

Quick approximation?? How can that be done..

#45 Re: Help Me ! » Easy way!!! » 2010-05-31 00:26:37

I got to get the answer as 5.227 * 10^3

#46 Re: Help Me ! » Summation » 2010-05-31 00:19:15

So the only way I learn it is by doing a lot of problems of this kind.

Is there some easy way or trick to solve these easily

I know this is silly , but i want a very easy way to solve this..

I take a lot of time in these calculations
