Natural or artificial product awareness!!

how many of you think that colour mark on toothpaste tube or other product represents their contents..(i.e. pure natural, or chemicals used!!! like
green for all natural product,
brown for natural + medicine
red for natural + chemicals
black for pure chemicals
these are nothing but utter bullshits...!!!
these are in fact....
The colored squares on the tubes have no relationship with the content of the toothpaste. They are known as ‘color marks’ or ‘eye marks’, which are articles of the manufacturing process. These marks show whether the packet can be either folded or cut as interlocking units stream through machinery at a high speed and the markings can be seen using light beam sensors.
please don't buy your product on the basis of these coding...
or on the basis of any advertisement claming to be all natural product.
most of them use some form of chemicals like food additives and many other chemicals which they don't even disclose...!!
judge a product before buying and do a proper market survey as alternate and better  product are generally available under your required category.

Ambition vs fantasy

There are different kinds of people some tend to live in a world of fantasy and do nothing to achieve it. They will spend their whole life agonizing that they didn't achieve what they desired. Then, there are people who don't have any real larger goals they just pass their time achieving short-term requirements they may be happy-go-lucky but their life is not so interesting as they don't have any ambitions or something to chase. Then there are those successful people who have real goals to achieve, who work hard to achieve them thinking day and knight about what they want to be and how to achieve them, they have everything pre-planned and well prepared for all aspects of life. They have the attitude to achieve what requires to be on top of the world and they work hard to achieve their dream. 

The person who don't have a ambition in life is just any other person in the world... His/her life is hell  lot boring. They don't have to do much & it may be possible that he or she may not enjoy the small things happening around them.
There are two types of ambition one that is aimed for longer duration and one that is aimed for short term & these short-term goals should be made in such a way that it is ultimately directed to the achievement of the larger goals... So make an ambition for your self which may be achievable, but don't leave in the world of fantasy And prioritize the goals which need to be achieved first and that to be achieved in the longer term. 
There are some drawbacks also in the process of achieving these goals people sometimes become over-ambitious and start ignoring the little things around them. It shouldn't be done in this way. Balance your ambition with the right amount of effort and enjoy all the sweet kinds of stuff around.. Leave happily...

USING YOUR CALCULATOR EFFECTIVELY

 The best calculators for Examinations which allow using Non Programmable calculator  are
Casio fx 991 es plus.
casio fx991ex etc.
Here I am explaining some important but lesser used functions of the calci. which every engineering students must know.
firstly ther are three types of inscription on calci keys.
 #one that is written in bold black or white :  this function or numeral can be accessed by simply             pressing that button.
#second is that written in yellow color that function be accessed by pressing SHIFT key before pressing that key function.
# third is that written in red colour .this key can be accessed by pressing ALPHA key before pressing that key
1. equation solving
   a) Equation in standard form
      #press MODE key
      #press 5 key for selecting EQN
     # choose the type of equation  by pressing the numeral key corresponding to it.
        suppose we have to solve 4x² +12x + 9=0

         to solve this we enter the values corresponding to a,b,c in format (Ax² + bx + c=0 )
         enter it as"4", "=",  "12", "=",  "9"         pressing ''=''    gives the first sol, again pressing  ''="                 gives second soln. for the problem.

 *  2) Equation in general form 
 solving above problem in non standard way...
write the above eqn  i.e.    "4x² +12x + 9=0"    in same format, writing vaiable    ''x''    by pressing ALPHA key then  '')'' key and write "='' by pressing ''ALPHA'' key then   ''CALC'' key.
for sol press  ''SOLVE"  key( it can be accessed by pressing SHIFT the CALC key)
then press main     ''='' key and get the results .
* equation of  even higher degrees can be solved by this procedure


3)Use of  calci. for definite integration:     

2. matrix operation.
  a) matrix multiplication
# press MODE key
#select matrix by pressing 6
press  AC   then   SHIFT
press 4
press 1 for selecting DIM
press 1 for selecting MAT A
select type of matrix and input data
press AC
press SHIFT then 4 then
select DIM by pressing 1
select type of matrix
input value then press AC
press  SHIFT then 4
Press 3 then press SHIFT THEN 4 then 4 for MATB
press =
  b) inverse of matrix
  c)determinant of matrix
3. Indefenite integration
