As you can see, it slowly alternates between other numbers and 1/2, but the difference between the alternates diverges to zero as the number of partial sums increase, thus, the equation does diverge to one-half. > What is 1 divided by infinity?

It looks like from the positive data set (from the table on the right) that zero to the negative one power (0 ^ -1) approaches positive infinity. The closure of the natural numbers under addition means that the sum of any two natural numbers is a natural numbers. converges to a finite value as long as the power is a number greater than . you see when you look at the world at very small scales. Want facts and want them fast? Z = 1/2. Basic linear eqn If you are working with limits, it depends on the expression. That plane is called the complex plane.

Illustration of the Casimir effect. York Times. Shouldn't more maths teaching and learning emphasise this? do you know what solving an equation means? that when you add up all the natural numbers. It says Being wrong, is simply wrong. The mathematics of zeta functions is fantastic and what we described here is just the start of a long list of amazing mathematical properties. Just as you can define functions that take real numbers as input you can define functions that take complex numbers as input. it looks like a math error to me. So how did the people in the Numberphile video "prove" that the natural numbers all add up to -1/12? Non-convergent series are unpleasant and subtle things most 1st year mathematics text books will tell you the convergence properties of this sum. And while the real numbers correspond to all the points along an infinitely long line, the complex numbers correspond to all the points on a plane, containing the real number line. So it seems that nature has followed the ideas we explained above. Z is not an unknown variable. Likewise functions with x 2 or x 3 etc will also approach infinity. Very good, the naturals are closed under addition. It is used to identify the infinite series 1-1+1-1+1-1+1-........ 1 - (1-1+1-1+1-1+1-1+...) = 1-1+1-1+1-1+.....

You can't contradict a statement and substitute it with a value since the person is still trying to find the value.
