read abt ur marks in another post. best of luck for ur rank in iitjee.
i shall be thankful to you if you comment on my physics marks

i am in XII this year .HENCE I KNOW ONLY XI th iit SYLLABUS i solved this years iit paper. and managed the following marks-

Phy- 60

chem-55

maths-78.

TOTAL- 188

CAN I GET INTO IIT THIS YEAR.

cutoff will be close to 35-40%. maths cutoff maybe 45% or so.

a perfect explaination of the complex concepts in a simple manner

i am in huury, i cn tell u d method. first find the radius of this circle.incentre is equidistant frm d sides. hence u will gt 3 equations for 3 sides in x and y. we know that coordinates fr incentre is x= ax1 + bx2 +cx3 / (a+b+c) ; y= ay1 + by2+ cy3 /(a+b+c) where a,b,c are lengths of BC AC and AB resp. u will get 3 more eqns for 3 sides. solve them to get the eqns of sides and find their pt of intersection.it will be the vertices. now the circumcentre is equidistant from 3 vertices and hence u will get its radius and centre and hence d eqn

it is b,c for sure.

it is b,c for sure.

there are so many gud buks available, and if one goes thru them thoroughly, then everything from the package is automatically covered.
