Re: mirror help me!Do you have the picture?

Re: mirror help me!I thought you had figured out how to post a picture? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20131116 23:34:57
Re: mirror help me!Alternately you can upload the picture in a familiar site and post the image hotlink here 'And fun? If maths is fun, then getting a tooth extraction is fun.

Re: mirror help me!It is in post reply on the bottom, I can make a picture of it if you need it. In mathematics, you don't understand things. You just get used to them.

Re: mirror help me!What a coincidence! This is the same question I encountered while taking the IIT JEE some years back. The answer is 30. I have discovered a truly marvellous signature, which this margin is too narrow to contain. Fermat Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.

Re: mirror help me!hi niharika_kumar This can happen until it has travelled 2root 3 in that direction. Say it happens n times then But the ray has also hit A at the start so add one, but 'just' misses B at the end so take one off. Hence the maximum number of reflections is 30.

Re: mirror help me!Niharika, you are preparing for the JEE? I have discovered a truly marvellous signature, which this margin is too narrow to contain.

Re: mirror help me!JEE is my goal and its preparations are going in parallel, but now I am in class10 so my focus is more on boards. friendship is tan 90°. #16 20131121 04:16:54
Re: mirror help me!What is JEE? Joint Entrance Examinations? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: mirror help me!
Just saw this post right now... I have discovered a truly marvellous signature, which this margin is too narrow to contain.
