** Almost many Students try to overcome the hardness of the Mathematics and Physics subjects. Students tried to skip out the difficulties from the difficult subjects like wise Mathematics and Physics etc. Since its contains more numerical and mathematical stanza. They spend more time practising and memorizing the formulae from their syllabus**.

# What do you know about formulae?

*Formulae means nothing but the equation symbols for finding an unknown absolute value.*

It is usually represented by the **Alphabetic** and **Numerical** symbol, Greek’s and Latin’s words etc. by an ancient People.

## Types of an Equation Formulae

**1. Simple numerical formulae**

**2. SI units formulae**

** Simple numerical formulae**:

*It is the formulae represent just to find the scalar value or mathematics value. Mostly it is used in the mathematics subjects, to find the absolute value of an unknown value which evaluated from the known value. Sometimes it is also used to find out in case of an error values.*

For example *Trigonometry* and P*robability* formulae are some of the example of simple numerical formulae in mathematics.

## Tan⊙=sin⊙/cos⊙

Which does not include any symbol of the measurement units, but its represent just the simple ratio of numerical value.

* SI Units formulae*:

*It is the physical formulae to find the unknown value which is used in combination of the scalar value and units symbol. It is also very useful in our day-to-day life.*

While reading a books unless you know the meaning of every single words you couldn’t understand the whole sentences of the books. Similarly while trying to memorize the formulae unless you know the meaning of the symbols in the equation, you cannot memorize the whole formulae in the equation.

Memorizing the symbols given on it, is not important but to memorize the meaning/uses of the formulae is the main things. Example we have familiar the common *relativity* formulae which is given by symbol **E**(*energy*), **m**(*mass*), **c**(*velocity* *of light*) and the square is represented as the power of an exponential (power of its multiplication itself).

# E=mc^2

Before applying it in the solution, it must carry a method or the rule such that it can generated a correct term of the solution. Such as every symbol term are links each other. Some of it terms are independent (** constant**) otherwise all are dependent (

*) to one and other. So if you came to know one term of symbol you can be possible to understand the relation of the whole term of the equation.*

**varying**You might be wonder how hard you try to memorizing all sources of formulae at a time before entering examination room. You feel compatible but when you need to solve a question paper, your mind focus randomly, you are still feel confusing to applied the particular formulae.

This show that you are not in the mood of learnt it, the meaning of the formulae but you just by heard it yet.

### Tips of memorizing the Formulae

First of all by heard all the symbol term given on the formula

Look at its relationship including on the equation

Look at the solution required for as mention on it

Note down all the formulae on the sheets of paper

Fixed it in the wall, and try to memorize at least five a day

Classify yourself between the relation with constant term and varying term

Find its proportional relationship with denominator and numerator and vice versa

Practice it almost every day before your bed time

**Learning shortcut without knowing the exact meaning is not the permanent knowledge**

So instead to by-pass it without meaning, you better go to the long run of it, step by step. You should also be aware about from where this formulae come from and in which field it has been used.

## Behind the Examiner mind

I think you have heard about *competitive examination* classes. Teachers in this course they used shortcut of teaching the formulae, which they were not focus more important about the formulae. But they simply teach the technique how to by-pass the formulae, automatically can be generated into the result value.

While solving a numerical problems sometime you have to by-pass the simple term such that it should not take over, on your precious time inside your exam hall.

Try to pass it on with a small steps forward direct to your target result. Here the main important are only the initial point of your formula then next the result. The rests are just your calculating method.
