what is measurement
Everything that we use in our daily life is ultimately governed by principles of physics. All gadgets we use everyday at home, bicycles and cars, all different types of machinery and instruments, work on principles of physics. Hence to understand even the elementary working of these things, the study of physics is essential.
For understanding the relationships between matter and energy, measuring them is very essential. There are thousands and thousands of different things around us. There are different kinds of forces around us and there are different kinds of energies that we come across every day. Thus there would be millions and millions of physical quantities and energies that could be measured. Yet you would be surprised to know that there are only six basic units from which all other units are derived. This also helps us on water pollution statistics. These basic units are the units of length, mass, time, electric current, temperature and luminous intensity. Out of these only three fundamental or basic units of measurements are used in mechanics.

Note on Continuous Function
Definition of Continuous Function:
In study of probability, a Random Variable X is assumed as a continuous variable, if it can take all possible values within certain given limits. That is X is a continuous its values cannot be put in one to one associated with N.
A nonstop probability function f(x) is a function that satisfies the following properties:
- It is non-negative for all real X.
- The probability function of integral is one.
- Constant continuous probability functions are known as probability definition function (pdf).
- Since regular probability function are defined for uncountable number of
points over an interval, the probability at a single point is always zero.
The probabilities are measured between intervals। That Is, the area under the curve stuck between two distinct points define the probability for that interval.This can also help us on how to simplify radicals.
P(a ≤ x ≤ b) = P(a ≤ X < b) = P(a < x ≤ b) = P(a < x < b)
Discrete Probability function is referred to as probability mass function.
Continuous probability functions are known as probability density function

Note on Closure property of integers under addition
What is integers?
The negative numbers, zero and the natural numbers together are called integers.
For example -8, -2, 0,2,8
This was just a brief introduction to the topic . Keep reading and leave your comments. May be in the next lesson let me help you go through more on properties of logarithms.
