Use MATLAB

 • 1-calculate the first 100 iterations of 

                                ∑ ? ^2 ? ?=1 = ?(?+1)(2?+1) 6

 Note i is from 1 to n and in front of sigma we have i 2 

• 2- Estimate the value of π. 

(Help;                      ∑ (−1)^? 2?+1 ∞ ?=0 = ? 4 ) 

Note n is from 0 to and in front of sigma we have a fraction in top ( -1)^n and in the bottom of fraction we have 2n+1.
