%% Problem title 

%% (a) Title of first part 
% Description and comments 
% and observations
% and so on

format compact              % tells Matlab not to print blank lines between answers
v1 = [-1;2;2]
v2 = [2;-1;2]
innerproduct = dot(v1,v2)   % gives zero, i.e. v1 and v2 are orthogonal

%%  (b) Title of second part
% Description and comments 
% and observations
% and so on

x = 0:.1:10;                % use semicolon for stuff you don't want to print!
plot(x,sin(x),x,cos(x))
legend('sin(x)','cos(x)')

%% (c) Title of third part
% Note that Matlab is very picky about the format: 
%
% * The % and %% must start in the first column
% * There should be exactly one space after %% and %
% * You can generate a bulleted list like this
