Expanding according to the above, we have e2 2√ πik = cos(2 2–√ πk) + i sin(2 2–√ πk $\begingroup$ To rigorously justify the last step of finding the limit, use the fact that subsequence of a sequence converges to the same limit as the original, so $\lim a_{n+1} = \lim a_n = a$; then by the Algebraic Limit Theorem, we can manipulate the limits to simplify: $(\lim (a_{n+1}))^2 = a^2 = \lim (a_{n+1})^2 = \lim (2 + a_n) = 2 + \lim sqrt(x) Natural Language; Math Input; Extended Keyboard Examples Upload Random.6. Step 2. Hope this helps. Step 4.3. The square root calculator finds the square root of the given radical expression. You have: a/sqrt (2)= you can take the root of the numerator (which in this case is a=1) but you have always to square it (to avoid changing your fraction) so you get: sqrt (a^2)/sqrt (2) you can use one square root only: =sqrt (a^2/2)= but in this case a=1 so that 1^2=1 so you get =sqrt (1/2) The Square Root of Two to 1 Million Digits What follows are the first 1 million digits of the square root of 2.
