বাংলা মাধ্যমের প্রাথমিক শিক্ষার্থীদের একটু অন্যভাবে বা অন্যরকম অঙ্কের স্বাদ দেওয়ার জন্য দশটি লেখার একটি সিরিজ তৈরি করা হয়েছে । যার নাম দশকথা । আজ দশকথার প্রথম কথা। এই লেখাতে আমরা দর্পণ প্রতিসাম্যতা ব্যাপারটি বলব । আপনাদের মন্তব্য-প্রতিমন্তব্য চিন্তা গণিত কেন্দ্রের এই উদ্যোগকে এগিয়ে নিয়ে যেতে সাহায্য করবে ।
Remember the Dudeney puzzle introduced in the last post. We have ended with the question "Why four?"...We will be revealing the reason in this post.
IMO 2018 Problem 6 discussion is an attempt to interrogate our problem solving skill. This article is useful for the people who are willing to appear in any of the math olympiad entrances.
Understand the Problem: The polynomial \(x^7+x^2+1\) is divisible by (A) \(x^5-x^4+x^2-x+1\) (B) \(x^5-x^4+x^2+1\) (C) \(x^5+x^4+x^2+x+1\) (D) \(x^5-x^4+x^2+x+1\) Solution A shorter solution or approach can always exist. Think about it. If you find an alternative solution or approach, mention it in the comments. We would love to hear something different from you. Also Visit: I.S.I. & C.M.I […]
" Take care of yourself, you're not made of steel. The fire has almost gone out and it is winter. It kept me busy all night. Excuse me, I will explain it to you. You play this game, which is said to hail from China. And I tell you that what Paris needs right now […]
INMO Camp is in full swing at Cheenta. So is the new Research Track program for young researchers in school and college. What is happening at Cheenta this week.
Pedal triangles lead to spirally similar cyclic quadrilaterals in any triangle. A half turn and dilation by 1/8 create the new quadrilateral.
30 sessions, 45 hours, a team of 6 faculty members. Cheenta is presenting a camp for Indian National Math Olympiad (leading to International Math Olympiad). We begin on 14th December 2018 and it will run up to 19th January 2019.
We fold a paper using GeoGebra and explore a problem from American Mathematical Contest
From Hilbert to Thurston, Clairaut to Dunwoody, we explore competing methods of writing mathematics. They form the philosophical basis of Cheenta Classes.
