A Cunning trick in Maths
Using tricks in Maths, it is even possible to prove that 1=2 (?). This can be done as giver below:
let a=b, where a and b are 2 non-zero numbers.
or, a2=ab,
or, a2-b2 = ab- b2
or, (a+b)(a-b) = b(a-b),
or, (a+b) = b,
or, 2b = b,
or, 2=1 (!),
by this way, we can prove that 1=2. Isn't it funny? I know that many of my Dear friends are interested to find out the trick, and for them I'll publish the trick in my next session.
Well, I hope you liked the trick, and many have found out the wrong in it. Let me point out the wrong line. It is, if a=b, then certainly (a-b) = 0, and so, although
(a+b)(a-b) = 0 = b(a-b),
(a+b) not equal to b. So, the relationship doesn't stand valid.
How to reset the Microsoft Office 2007 product Key?
Many of us, (like me) might have been using Microsoft Office 2007, but perhaps it is unknown to many, how to reset the Microsoft Office 2007 product key. Suppose we've bought the license from Microsoft, but the trial can not be converted to Full Version immediately. Then we can try the following:
Go to Run, and type regedit which will open the Registry Editor.
Now, expand Local Machine -> Software -> Microsoft -> Office -> 12.0 -> Registration.
Next select the product you want, and modify the binary data content of the values Digital ProductID and ProductID to 0 0 0 0.
Now, run any office Program, and it will ask for the license Key. Now, enter a license key, and the Product will be activated.
