Write a function called sindeg that takes a matrix input called deg. The function returns a matrix of the same size as deg with each of its elements containing the sine of the corresponding element of deg. Note that the elements of deg are given in degrees and not radians. As a second output, the function returns a scalar that contains the average value of the first output. You are not allowed to use the sind and cosd built-in functions, but the use of any other function is acceptable.
My answer is
function [sine, mean_sine] = sindeg(deg)
sine = ;
mean_sine = sum(sine) / length(deg);
I couldn't fill sine because I dont understand that. Please guide me about this.

You just need to convert the degrees to radians then...
https://en.wikipedia.org/wiki/Radian
function [sine, mean_sine] = sindeg(deg)
% Convert to radians
my_radians = deg * pi/ 180.0;
% Use the sin function
sine = sin(my_radians);
% Work out average
mean_sine = mean(deg);
end

function [sine, mean_sine] = sindeg(deg)
my_radians = deg * pi/ 180.0;
sine = sin(my_radians);
avg = (mean(sine));
mean_sine = sum(avg) / length(avg);
This will hopefully solve the problem :)
