Science > Chemistry > States of Matter > Introducion A matter is defined as anything that has mass, which occupies space and may be perceived by senses. There are three states of matter, viz. (a) solid, (b) liquid, and (c) gaseous states. Whatever may be the state of matter, it is composed of particles. In […]
In the previous articles, we have studied the basics of set theory and its terminology. In this article, we shall study operations of sets including Union of sets, Intersection of sets, a complement of a set, Cartesian product of sets. The basic operations on sets are: Union of sets Intersection of sets A complement of […]
A set is a collection of well-defined objects. These objects may be actually listed or may be specified by a rule. Sets are denoted by a capital letter like A, B, C…. and an object belonging to them (element of the set) are denoted by a small case letter like a, b, c,… of the […]
Science > Chemistry > Introduction to Chemistry > Properties of Substance All matter has physical and chemical properties. Extensive properties are those properties of a substance which depend on the amount of substance. They vary with the amount of the substance. Examples: Mass, weight, and volume. Intensive properties are those properties of a substance which do not depend […]
Law > Medical Jurisprudence > Contractual Doctor-Patient Relations A doctor–patient relationship (DPR) is considered to be the core element in the ethical principles of medicine.

Example 01: Expand (a + b)2 Solution: Expanding Binomially (a + b)2 = 2C0a2 + 2C1a2-1b1 + 2C2b2 (a + b)2 = (1)a2 + (2)a1b1 + (1)b2 (a + b)2 = a2 + 2ab+ b2 Note: (a – b)2 = a2 – 2ab+ b2 Example 02: Expand (a + b)3 Solution: Expanding Binomially (a + […]
Science > Mathematics > Algebra > Logarithms > Use of Laws of Logarithms Set – III In the last article, we have studied to solve problems on the use of laws of logarithms to prove given logarithmic expression. In this article, we shall study to solve more problems on these laws to prove given relation […]
