- 5. Show that the infinite sequence an = that it is monotone and bounded. You do not need to find the limit of the sequence. Vn2 + 1 – yn² – 1 (n 1) converges by showingarrow_forwardThe improper integral 1 xp- (x + 4)4 is convergent. Select one: True Falsearrow_forwardCalculate whether it is convergent or divergent.

- 4. Let a₁ = 1 and an+1 = √8+ an Show that the sequence {an}1 is convergent and find its limit.arrow_forwardIdentify two subsequences of ((−1)^n + 1/n) which converge to different limits. You should include explicit formulas for the selector functions.Pick one of your two subsequences and write a proof of the fact that it converges.arrow_forward8. Determine whether the improper integral re dr is convergent or divergent, and evaluate if convergent.arrow_forward
- If x1, y1, are two positive unequal numbers and xn = (xn-1+ yn-1)/2 and yn= sqrt(xn-1yn-1) for all n>=2, Prove that the sequences <xn> and <yn> are monotonic and they converge to the same limit. *Prove each steparrow_forwardThis question is from real analysisarrow_forwardUse the definition to prove that {1+2}converges and limn→∞ (1 + ²) = 1arrow_forward
- Suppose the function f(x) has a unique zero P in the interval [a,b]. Further, suppose f''(x) exists and is continuous on the interval [a,b]. a. Under what conditions will Newton's Method give a quadratically convergent sequence to P? b. Define quadratic convergencearrow_forward* Show that the sequence (xn)n21 in R, where 1 In =1- converges to 1.arrow_forwardDecide whether the following proposition is true or false. Provide a justification for your answer: If (x,) is bounded and divergent, then there exists two subsequences of (x„) that converges to different limits.arrow_forward
