Do you know that CLOCKS add numbers in a different way than we do? Do you know that ROTATIONS can also behave as numbers and they have their own arithmetic? Well, this post is about how clock adds numbers and rotations behave like numbers. Let's learn about clock rotation today Consider the clock on earth. […]
Shortest path between two smooth curves is along the common normal. We use this fact to solve 8th problem of I.S.I. Entrance 2019 (UG Subjective)
Indian Statistical Institute B.Stat, B.Math Entrance 2019 (UG Answer Key, Sequential Hints and more)
ISI BStat 2019, Subjective Problem 2 involving solving a limit to find the functional form of a function and its point of discontinuity by Sequential Hints.
ISI Entrance 2019, Subjective Problem 3 involves sketching a set of complex numbers. We provide sequential hints that leads to solution.
Inequality of fractions An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size. In this post we are going to discuss a problem on inequality of fractions. Try the problem This problem is from Indian Statistical […]
PRMO 2017 (pre regional math olympiad) has this beautiful geometry problem of circle in a circle. Try with sequential hints.
Boundaries are controversial. Ask the politicians! Mathematicians, on the other hand, have an interesting way of thinking about the boundary of the space. It is less controversial for sure.
A beautiful geometry problem from Math Olympiad program that involves locus of a moving point. Sequential hints will lead you toward solution.
Date: April 20, Saturday, 6 PM I.S.T. Abstract A great way to study groups is to study group automorphisms. They are structure-preserving maps from a group to itself. Some subgroups are 'invariant' under all group automorphisms. They are known as characteristic subgroups. One example of the characteristic subgroup is the commutator subgroup. In this seminar, we […]
