In Mathematics, A theorem for Sequences says that, If a sequence of real numbers {an}nN has a limit, then this limit is unique. Convergent Sequence. That means you can take the second sequence you need to squeeze with to be, \[ \{ t_n \} = \left\{ -\frac{1}{n} \right\}. The sequence can be simplified by multiplying the bases and raising them to the same exponent: You can see looking at the picture above that it doesn't matter how large an \( M \) you pick, there is no way to get all of the sequence values to be between the two lines \( y = 1 + \epsilon \) and \( y = 1 - \epsilon \). If the sequence has a limit, the limit would need to be either \( -1 \) or \( 1 \) since those are the only two values in the sequence and they don't change at all. Here, the function is the ratio of two polynomials & the limit value is zero or infinity. That means this sequence doesn't converge. Better than any school, even 6k per year schools that I go to. The input expression must contain the variable n, and it may be a function of other variables such as x and y as well. If a sequence converges, it has a unique limit. Fig. But, \[ \begin{align} \lim\limits_{n \to \infty} (s_n \cdot t_n ) &= \lim\limits_{n \to \infty} n \cdot \frac{1}{n} \\ &= \lim\limits_{n \to \infty} 1 \\ &= 1 . Limits can be defined for discrete sequences, functions of one or more real-valued arguments or complex-valued functions. Formally, a sequence S_n converges to the limit S lim_(n->infty)S_n=S if, for any epsilon>0, there exists an N such that |S_n-S|N.
