(sorry,can't post pics,somethings wrong with my browser and my english is also shaky)
if n diameters are drawn in a circle than 2n triangles are drawn,n on each side of a specific diameter.for every triangle there is a congruent triangle on other side(2 sides are radii,interior angles are vertical) thus n triangles on one side are congruent to n on the other side.as n tends to infinity the area becomes equal to other sides area.so, both sides have equal area.

A wheel has 2 circles,interior and exterior.the interior circle obhiously has smaller circumference.now suppose the wheel is rotated 5 times and it has crossed 10 m then the exterior circle's circumference is 2 m. But the interior circle is also rotated 5 times and it is also 2 m.so,both circles are same! How is it possible?

Never mind,i've found a proof.

This proof isn't actually needed by me,but i am curious how to prove it,"the diameter of a circle divides the circle into 2 equal parts"

If f(a,b)=f(b,a) and f(a+b,c)=f(a,c)+f(b,c) then what are the solutions for f?

That's also a proof,you are proving that the given proof is false.

#87 Re: Science HQ » The Big Bang Theory... » 2013-06-01 12:45:02

You're right bobbym,that's why math is my favorite topic,I love to see theorems  being proved

Hi bobbym,you're gonna have to give me more than that,all i know about internet is how to browse.

#89 Re: Help Me ! » Postulates » 2013-06-01 00:47:05

I didn't really understand the proofs,and by the way how do you post links?

#90 Re: Science HQ » The Big Bang Theory... » 2013-06-01 00:08:14

Yes,we cannot be certain about anything unless we believe in it.

#91 Re: Science HQ » The Big Bang Theory... » 2013-05-31 23:47:31

You're right,theories change,people used to believe earth is flat,then they believed earth is the centre of the universe,all these changed.

They spread the news because man cannot live without explaining something.

#93 Re: Science HQ » The Big Bang Theory... » 2013-05-31 23:18:35

You know,science actually doesn't give answers,it only gives theories(probable answers)

#94 Re: Science HQ » The Big Bang Theory... » 2013-05-31 22:34:07

Why does power have to come from somewhere else?the answer is logically or according to rules.but logic works in the universe only,if there was no universe,there was no logic.

#95 Re: Science HQ » The Big Bang Theory... » 2013-05-31 22:09:22

Why does there have to be something before big bang(this may seem dumb,but actually i have thaught about it)

How can playfair's postulate be proved from parallel postulate and vice versa?

#98 Re: Help Me ! » basic calculus » 2013-05-29 04:28:43

I agree with you bobbym.my friend constantly asks me what the notations mean.

#99 Re: Help Me ! » basic calculus » 2013-05-29 03:43:25

Why do some people like calculus so much?one of my friends is eager to learn calculus,but he hates other maths!

Sorry,i mistook.by the way why won't 27 to 36 work for the first problem
