P&C IITJEE Problem - Find the Probability that 2 Boys are sitting Opposite Link: https://youtu.be/4EUFUT5GT2E . Suggested Book: Title: Mathematics for IIT-JEE Link: https://amzn.to/3gIk5XQ . There are 40 chairs and 17 boys. All the chairs are placed around a circular table such that distance between any two adjacent chairs is same. All the boys are randomly sitting on the chairs. What is the probability that exactly two boys are sitting opposite to each other (on the ends of any diameter)? . . #iitjee #neet #jee #iit #jeeadvanced #jeemain #jeemains #cbse #physics #education #chemistry #kota #engineering #aiims #science #neetpreparation #maths #iitjeepreparation #mathematics #student #exam #memes #neetug #exams #kotacoaching #iitcoaching #iitjeeonline #iitbombay #sciencememes #mathematicalmindsets https://www.instagram.com/p/CDrBqKqjbAM/?igshid=gs5vrrvhzesp

Fake Coin Logic Puzzle - The Seemingly IMPOSSIBLE Counterfeit Coin Riddle Link: https://youtu.be/Sw2oBIlnnRY (Link also in bio) . There is a kind of hydraulic weighting balance which has three pans. There are thousand gold coins and one of them is fake. The fake coin is slightly heavier than others. You can use the hydraulic balance to compare the weight of three objects at once but can’t get the exact reading of weights. You have to find the fake coin in minimum number of trials. What will be your strategy and in what number of trials you will surely find that coin? .

The Cubic Formula: Roots of the General Cubic Equation Link: https://youtu.be/Sjj3Z43NUz8 . Why is it that, unlike with the quadratic formula, nobody teaches the cubic formula? After all, they do lots of polynomial torturing in schools and the discovery of the cubic formula is considered to be one of the milestones in the history of mathematics. It's all a bit of a mystery and our mission today is to break through this mathematical wall of silence! Lots of cubic (and at the very end quartic) surprises ahead. . Suggested Book: Title: Cubic Equation Solver - Solve cubic equations easily! Link: https://amzn.to/2CVajTL . In algebra, a cubic equation in one variable is an equation of the form ax^3+bx^2+cx+d=0 in which a is nonzero. . The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation. If all of the coefficients a, b, c, and d of the cubic equation are real numbers, then it has at least one real root (this is true for all odd-degree polynomial functions). All of the roots of the cubic equation can be found by the following means: . # Algebraically, that is, they can be expressed by a cubic formula involving the four coefficients, the four basic arithmetic operations and nth roots (radicals). (This is also true of quadratic (second-degree) and quartic (fourth-degree) equations, but not of higher-degree equations, by the Abel–Ruffini theorem.) # Trigonometrically # Numerical approximations of the roots can be found using root-finding algorithms such as Newton's method. . The coefficients do not need to be real numbers. Much of what is covered below is valid for coefficients in any field with characteristic other than 2 and 3. The solutions of the cubic equation do not necessarily belong to the same field as the coefficients. For example, some cubic equations with rational coefficients have roots that are irrational (and even non-real) complex numbers. . #cubic #formula #cubicformula #cubicequation #equation #cubicfun #number #general #generalcontractor #Math #quadratic #quadraticequations #cubicequations #eqn #MATHS ##mathema #learning #onlinelearning #learn #online #internet #data #mathsislife https://www.instagram.com/p/CDRkWuQjKXE/?igshid=1mw569t6w2fnj

Trick - Calculate Logarithm Without Using Log Table Link: https://youtu.be/cUA1XMAGNEc . A logarithm is the power to which a number must be raised in order to get some other number. For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2 because 10^2 = 100 This is an example of a base-ten logarithm. We call it a base ten logarithm because ten is the number that is raised to a power. The base unit is the number being raised to a power. There are also logarithms using different base units. .
