How to prove a given equation in Mathematics exam???
1. Try out the formulae you’ve learnt in Math class (provided you were paying attention, which you most likely weren’t.)
2. If your answer turns out right then you got lucky, pal.
3. If your answer isn’t right, then your options are very few:
3.1. The Topper Method – You realise that a direct substitution of aforementioned formulae is not the way to the answer. You thus proceed to create the “asli formulae ke sahi mishran” to get the answer. (Note- Any hair loss due to pulling out your hair is to be ignored. What’s important is that you GOT THE ANSWER, albeit by “eating your morsel of food from around your head”, as the old adage goes.)
3.2. The Non-Topper Method
3.2.1. Scratch your head.
3.2.2. Bang your head on the desk.
a. Curse your stars, the teacher (for setting such a tough paper), the topper of the class (for being a topper and knowing the answer. Why do toppers even exist, besides being at the receiving end of any and all curses???), the invigilator (for not letting you cheat from said topper’s paper), your tuition teacher (for not marking that particular question as important). Basically everyone in the world, except yourself.
b. Now proceed to curse yourself, for all the playing and loafing around, the late night T.V. shows., Internet surfing and chatting with friends (and/or your boyfriend/girlfriend), all when you could’ve been studying.
3.2.4. Waste half an hour trying to recollect the questions you RATTOFIED the previous night.
4. Now completely bald from pulling out all your hair, you’re absolutely sure that you are getting a zero for the question.
But then you remember the famous lines: “Zindagi mein haar kar jeetne waale ko Baazigar kehte hein.”
Thus inspired, you proceed to go down valiantly and try the “To Zero and Nothing Beyond!” Theory.
5. Multiply LHS and RHS by 0.
6. Now since the LHS and RHS are equal i.e. they’re both zero, the statement given in the question is proved.
(Note- In your valiance and joy you have conveniently forgotten that the teacher may apply the same theory on your paper and give you a big 0 – zero. But, who cares? You got the answer!!!)
