The arrow will hit the target exactly at $t=L/v$ seconds. Origin $x_i=0$ and that the target is at $x=L$ metres. Suppose that the archer who fired the arrow was at the Where $x_i$ is the initial location where the object starts from at $t=0$. Then its position $x$ as a function of time is given by If an object is moving with constant speed $v$ (we ignore the The poor brother didn't knowĪbout physics and the uniform velocity equation of motion. We need to combine aspects of both of the above stories The wonderful Greek language with letters like $\epsilon$ and $\delta$, The monks have the right reasoning but didn't have the right They went back to concentrating on their breathing. “Even then, I can make it smaller, yet still not zero.” said the first monk victoriously and then proceeded to add “In fact, for any magnifying device you can come up with, you just tell me the resolution and I can make the thing smaller than can be seen”. “I can make the thing so small that even with a microscope you cannot see it.” “If I know that you will be looking with a magnifying glass, then I will make it so small that you cannot see with you magnifying glass.” ![]() The first monk was happy to hear this question, because he had already prepared a response for it. I could see it using a magnifying glass?”. “What if, though I cannot see it with my naked eye, The second monk didn't know what to say, but then he found a counterargument. “Yes, but what if no matter how close you look you cannot see it, yet you know it is not nothing?”, asked the first monk, desiring to see his reasoning to the end. “No,” replied the second monk, “if it is something then it is not nothing.” “Can something be so small as to become nothing?” asked one of the monks, braking the silence. The limits of integration are further applied to the solution o the integrals to find the final numeric value. The limits of integration for the function f(x) is \(\intab f(x).dx\) and here a is the upper limit and b is the lower limit. Two young monks were sitting in silence in a Zen garden one autumn afternoon. The limits of integration is generally given before the start of the integral function. Imagine if Zeno tried to verify experimentally his theoryĪbout the arrow by placing himself in front of one such arrow! I mean a wrong argument about limits could get you killed for We better learn how to take limits, because limits are important. Was invented (17th century), but shouldn't repeat his mistake. Him for thinking about such things centuries before calculus Limit argument, but he didn't do it right. Zeno, my brothers and sisters, was making some sort of Getting closer and closer to the target, but never reaches it. Later instant when the arrow will have travelled half of Zeno observed that no matter how littleĭistance remains to the target, there will always be some ![]() Half of the remaining distance and so on always getting closer Suppose an archer shootsĪn arrow and sends it flying towards a target.Īfter some time it will have travelled half the distance,Īnd then at some later time it will have travelled the The ancient greek philosopher Zeno once came up with
