Find the equation of the circle passing through the points P(1,1) , Q(2,-1) and R(3,2)
Hello There,
The general equation of a circle is given as :
x^2 + y^2 +2gx + 2fy + c = 0
Now if the circle passes through these three points then obviously these three points satisfy the equation of circle. So
For point P , we have
1+1+2g+2f+c=0 (eqn.1)
for point Q, we have
4+1+4g-2f+c=0 (eqn 2)
for point R, we have
9+4+6g+4f+c =0 (eqn 3)
Solving these three equation we get that ;
g = -5/2 f = -1/2 and c = 4
So the equation of circle is given by, putting the values of f, g and c in the general eqn of circle.
eqn = x^2 + y^2 - 5x - y + 4=0
Hope this helps.
I am passed out in 2006..if i appear for Improvement exam.which syllabus i will follow..I need to improve maths only..so i can give maths exam only..please let me know .when exam will start.
Hi,
You have not mentioned the board for which you want to appear for improvement exam. However, if it is CBSE, then you cannot appear for improvement exam. The rule for improvement exam is , a candidate can appear for improvement exam in succeeding year only. It means if you have passes your board class in 2006, then you were eligible up to 2007 only until you have not pursued higher studies. You can mention the board if it is other than CBSE, however, in most board improvement exam can be given in successive year only.
I dont have math in my passing certificate as i failed...But later passed in compartment.But still I dont have it listed in Passing certificate.But i have passed compartment marksheet for maths exam..So can i join NITs as i have all other thing eligible.
Hello Debayan
You are eligible for applying for NIT's if your total percentage are above 75% and as you have passed maths you there should be no problem for you but you should ask your school for the corrected passing certificate which says you have passed maths or else it can be a problem for you if they say your compartment marksheet will work then use that in time of verification and you shoudn't have any problem then
Hope this helps you

Hi Dear,
No, you'll not be eligible for Economics hons at University of Delhi, if you study maths separately from NIOS. To be eligible for Economic hons course at DU a student must have studied and passed Mathematics at the qualifying exam with atleast 45% marks in aggregate.

Good Luck
I had done 12th pcb in cbse board and applied for maths exam in nios, then i will be eligible for taking admissions in engineering colleges or universities like RGPV etc ?
Hello Vishal!
Yes why not? After passing the Maths subject from NIOS, the grades or marks of the maths subject will add on to your PCB senior secondary passing certificate and marksheet. And then you will meet the requirements of pursuing an engineering course as you passed with PCM subjects in 12th.
NIOS results are accepeted and recognized throughout the country. So, there is no need to worry about your admission in your preferred colleges.
Hope you are clear!

Banaras Hindu University is a top tier University and also the BSc mathematics course is highly famous among students and their for the cutoff is extremely high each year.
Indore last two three years the cutoff for BSC mathematics for for the female group was around 152.
for females and OBC category students the cutoff in the last few years was around 130, same as that you got.
with your category OBC and marks. I think you have very strong chances of getting your preferred course.
But please be patient and keep checking their official website.

hi,
see the general eligibility criteria is candidates wish to pursue b.sc in computer science must have studied mathematics as a subject in 12th course from a recognized education board. now many students studied additional subjects from NIOS, which certificate a acceptable in all Institute in India. so it depends on the recognized institute from where you have completed the bridge course. I suggest you to contact with the admission authority before applying any course and go through the Information brochure before applying.

Hey aspirant,
Congratulations for scoring so well in BHU UET!
BHU is one of the well renowned Colleges that set up its cut offs really high. But your category score and rank which you have acquired are enough to get you an admission in BHU for Maths hons.
Last year's OBC cut off rank for maths hons. was 707 and cut off score was 165.
Although cut offs may vary slightly year to year but your chances of admission are quite high.
Hope this helps,
All the best!
