 Basic Properties of LogarithmThis article is basically for all those students who have just entered in 10th/11th classes. When you start working on some difficult level questions on Mathematics, use of “Logarithm” comes automatically. However, only a basic knowledge of Logarithm is required to gear up initially which I am providing as below :Definition of Log : logy x = z    means         x = yzlogy x is pronounced as “log of ‘x’ to the base ‘y’ “Note : a.     ’x’ and ‘y’ MUST

 Numerical Approximations – The good, bad and the ugly – In this article, I will discuss about the application of Numerical Approximations as in XIth and XIIth class Standard level. I will discuss what a numerical approximation is, how it should be applied and how its application may come out to be good, bad or ugly. Please note that the below definitions/applications are not standards and I have tried to express the same based on my perception and experience. I will try to pull some examples from Chemistry where the concept can be applied. So, here we go –What is a Numerical Approximation ?It is a way to solve a numerical equation easily

  Pigeonhole Principle Here's a challenging problem with a surprisingly easy answer: can you show that for any 5 points placed on a sphere, some hemisphere must contain 4 of the points? How about an easier question: can you show that if you place 5 points in a square of sidelength 1, some pair of them must be within distance 3/4 of each other? If you play with this problem for a while, you'll realize quickly that the extreme case occurs when 4 points are at the corners of the square with a 5th point at the center. In this case adjacent points

Why?Well, there isn't a closed-form expression for the antiderivative of the integrand, so the Fundamental Theorem of Calculus won't help. But the expression is meaningful, since the it represents the area under the curve from 0 to infinity.Furthermore, there is a nice trick to find the answer! Call the integral I. Multiply the integral by itself: this gives I2 = then view as an integral over the first quadrant in the plane: I2 then change to polar coordinates (!): Now this is quite easy to evaluate: you find that. This means that I, the original value of the integral you were looking for, is . Wow! S

DOUBLE BOND EQUIVALENTS or INDEX NUMBER:It is a numerical value on the basis of which we can have an idea about the different type of equivalent structures we can have for a given formula. Knowing the DBE the problems on structural isomerism can be more easily solved. Mathematically,  DBE= {( n(v-2))/2}+1where n is the number of atomsv is the valency of the atom.Eg 1):Consider C4H6DBE={4(4-2)/2+6(1-2)/2}+1={(8-6)/2}+1=2This implies that the molecule may contain,1)two double bonds or one triple bond.2)one ring and one double bond.3)two rings. Thus by knowing the DBE total number of structural isomers can be formulated. Eg 2):Co
