Answer #1

Problem is solved using Octave open source compiler similar to MATLAB

#####MATLAB CODE

clc;
clear all;
%write given array
A=sin(-pi/2):0.05:cos(0);
[M N]=size(A);
fprintf('Number of elements in given array=%d', N)
B=A(1,10);
fprintf('\n\n10th element of array is %d', B)

########OUTPUT###

Number of elements in given array=41

10th element of array is -0.55
