i think there is a difference between undefined quantity and infinity. Just because we have not measured something does not mean it goes on for ever. Image an ant on a balling ball, it doesnt matter how far it crawls, it will never reach the end, it will crawl for ever but this does not mean the balling ball is of unlimited size . Blessed be

Well infinity goes on forever. Just because a quantity is nto yet defined we still know it's a limited quantity... Meaning not infinite :-)

An undefined quantity is one which is limited but not defined precisely. For example - People in a rock concert. The number of people attending cannot be defined exactly. The value can just be approximate. On the other hand, infinity is a very large number which cannot be counted. However, it can be defined.

Its simple if 1 divided by 3 = 1.3333333333333333...... here after the decimal 3 is repeating for how many time? it is infinity ( the value cannot be a known number but it is the last number) means we can understand the three is repeating for ever If 1 divided by 0 = undefined Because what ever be the number u take a quotient the result is zero means the division cannot be completed... Divison : Meaning is when dividend is divided by divisor the quotient is obtained till the remainder should be less than the divisor... In above the second example does not performing the divison so it is undefined.
