      x!0 sin(1=x) does not exist because of how the function oscil-lates near x = 0. However we can see from the graph below and the above theorem that lim x!0 x 2 sin(1=x) = 0, since the graph of the function is sandwiched between y = x2 and y= x2: O x K 1 K 0.5 0 0.5 1 K 1 K 0.5 0.5 1 Example Calculate the limit lim x!0 x 2 sin 1 x.

      Thus, any root of P(x) = 0 has order [7] 5 or 1 (in whatever eld it lies). The only element of order 1 is the identity element 1. If P(x) had a linear factor in k[x], then P(x) = 0 would have a root in k. Since [4] This assertion should not be surprising, when one looks at the technique of the proof, which is nearly identical

We therefore have a contradiction, showing that f(x) = 0 has at most one solution in the (1 ;1). Couple this with the fact that f(x) = 0 has at least one solution to conclude that this equation has exactly one solution in the given ...
