Can you find a point X on BC such that area of triangle XAD is equal to the area of triangle ACX?
Hint: Area and midpoint are intimately related.
Three Outstanding Programsfor brilliant students
Math Olympiad Program
Advanced number theory, geometry, combinatorics, and algebra.
This problem driven, rigorous program is taught by olympians, researchers who are active mathematicians at leading universities around the world.
I.S.I. & C.M.I. Entrance Program
B.Stat and B.Math Entrance Program at Indian Statistical Institute and B.Sc. Math Entrance at Chennai Mathematical Institute require special training in topics like number theory, geometry and combinatorics
This rigorous program for high school students is taught by students and alumni of I.S.I. & C.M.I.
College Mathematics Program
Entrances of TIFR, I.S.I. M.Math and Subject GRE require advanced training in topology, analysis, abstract and linear algebra.
This advanced program is designed to take you ‘inside’ the beauty of mathematics.
Cheenta is special …
Group class + One-on-One
Brilliant mathematics … personalized
Brilliant Faculty members. Problem driven sessions.
One mentor – one student.
Personalization of advanced math.
Inspiring problems every week. Mentors help students to solve.
“We contacted Cheenta because our son, Sambuddha (a.k.a. Sam), seemed to have something of a gift in mathematical/logical thinking, and his school curriculum math was way too easy and boring for him. We were overjoyed when
“Our experience with Cheenta has been excellent. Even though my son started in Middle School, they understood his Math level and took
I am impressed with their quality and professionalism. We are very thankful to Cheenta and hope to benefit from them in the coming years. I would strongly recommend them to any student who wants to learn Math by doing challenging problems,
In the coming week..
Join us in outstanding adventure in mathematics next week.
Euler's totient function
Euler’s Totient function gives the reduced residue class for a number. It has beautiful properties including multiplicative (group homomorphism). We explore it in a seminar.
Geometry of varingon
Varingon quadrilaterals are actually parallelograms. They exhibit deep connection between area and midpoint. We explore it in our Math Olympiad Group.
Fun with group theory
Characteristic subgroups are super invariants of a group in some sense. Commutator subgroup is one example of characteristic subgroup. We explore its properties in a seminar.
