Some Basics of Distance -time graph!!!

Distance-Time Graph is a graph where Y-axis represents distance traveled and X-axis represents time….
What we can determine from Distance-time graph?
1. We can determine the velocity( whether it is increasing or decreasing at a given moment)…
2. We can determine the Displacement…
3.We can determine the time taken to cover a given distance and so on………

//Let us Discuss very important part of Distance-time graph//

How to determine from a distance- time, that whether the velocity related to distance time curve is increasing or decreasing ?

For all this stuff you need to clear two of the very important concepts…

1.Tangent function is an increasing function in the interval [- 1.57,1.57] => [0,1.57], a tangent function is nothing but tan@
(where @ is nothing but the angle in degrees), this usually we all study in the basic trigonometry in our junior classes
but to know a bit more about tangent function visit……

For your simplicity let me explain it to you in a simpler way all of you ,i suppose know that tan0=0 ,tan30=(1/3)1/2
and tan45=1 ,and tan60=(3)1/2, tan90=infinite… from all this you all can easily determine that as 90>60>45>30>0
tan90>tan60>tan45>tan30>tan0.. it implies tan@ is an increasing function….

2. A concave up curve is a curve shaped like a bowl whose hole is in the upward direction and Concave down is similarly
a curve whose hole is pointing in the downward direction……..

Now how to determine whether the velocity is increasing or decreasing from the given Distance-time curve….


Consider the two curve shown (a) is a concave upward curve and(b) is a concave downward curve , now consider the
angles shown in the graph(a) as you can determine from the graph that angle a < b < c therefore tana< tanb < tanc …
now you need to know that dx/dt that is ( ratio of differential change in distance to the differential change in time) nothing but
the tangent drawn to the curve at that point and that in turn is nothing but the velocity at that point ,so as the tangent function is
increasing therefore velocity is increasing ,similarly in the graph(b) the tangent function is decreasing and henceforth the velocity
is decreasing…..

So one thing you need to REMEMBER BY HEART is that a concave upward curve in a distance-time graph represents the INCREASING
VELOCITY and concave downward represents the DECREASING VELOCITY….

Also from the graph(a) determine that at a point p velocity is nothing but the tangent at that know more about tangent to a curve visit

TEN Best Blog Topics!!!….

I have seen people confused when it comes to selecting there Blog topics ,the problem is that either they are talented in many arts and henceforth find themselves confused or there are people like me who know so little about everything that they don’t know what to write but when i talked to a blog expert ( professional blogger) my confusion was somewhat clear…

Now with months of Investigation on blog topics i find ten of these topics as the topics which can really attract good traffic if well dressed and maintained .

  1. HOW TO MAKE MONEY ONLINE (this phrase is day by day getting popular in google search engine and due to recession people are trying to get some extra salary through internet and as a result blogs related to making money online are getting day by day popular)..
  2. CAREER AFTER INTERMEDIATE ( so if you are proper counselor and know about careers after intermediate and which college to join or not to join which is asked frequently by students, about various entrance exams you can start your blog in this very topic )..
  3. A BLOG ON YOUR PHOTOGRAPH COLLECTION ( if you think you posses great pictures you can expect yourself making money through net by selling your photo collections through your blog )
  4. ABOUT NEW TECHNOLOGIES BEING LAUNCHED ( if you are something like gadget loving you can write on new technologies, for instance about apple notepad it’s advantages and drawbacks , these type of blogs are on whole very popular)..
  5. IF YOU CAN COOK ( if you are good in cooking different dishes might be Italian ,Indian , fast food and so on… you need not to be a professional cook for all this)..
  7. HOW TO REMOVE DARK HEADS, HOW TO REGAIN HAIRS ( that is about natural fashionable that people like us do suffer ,if you do a little investigation on these topics you can remove your dark heads as well as help others in doing so)…

Invest Smartly!!!…

If you want to make Money and at the same time make it safe from market downfalls and from other insecurities , there are nowadays two simple ways where you can invest your money so that they are not lost in some way or the other, i find people feel comfortable investing in life insurances , that is good but for instance say a 40 year old person it’s worth useless to invest in such insurances because investing it such late will give you no profit instead you will find yourself stuck in healthy economic problem in future….

Two simple ways available for such persons and for all who want to save monthly..are as

  • To invest for a long time say 10 to 15 years SIP stands best from all other equity investment and stocks…SIP stands for Systematic Investment Plan ,in these plans you simply have to invest very little compared to life insurances and other policies.. You simply have to invest every month and ultimately you are saving every month which could have been easily wasted if you were not forced to invest it in an SIP in different ways..which are useless and worth waste of money…

To know more about Systematic investment plan visit the following link..

  • Another day by day becoming increasingly popular FOREX (foreign exchange), though it is not as much popular as other investment plans but i have seen people making great amount of money from that or making there full living from that.
  • A great advantage of FOREX is that you do not have to do anything everything is done by the company through whom you have invested , if there is a loss the company suffers and you are safe but the other hand if there is a profit which usually is you get the profit, isn’t it fun…
