Again, A homework problem need to be done by you. First it's unethical for someone else to do your homework.

Post your effort or idea on how to solve it, then others will help you.

Answer 1

[Moussa Attati]

function [PI,RelativeErr] = pi_func(n) 
P=0;
for i = 1 : n
    PI =4*(((-1)^(i-1))*1/(2*i-1))+P  ;  
    P = PI;
end
RelativeErr=1-(PI/pi) ;
end
