Calculate the sin and cos of a value in radians (in one function)?

I attempted to answer the question but I'm not sure if this is considered to be one function.
b = input('Enter a value ');
x=sin(b); y=cos(b);
disp('The sin of that value is ');
disp(x);
disp('The
cos of that value is ');
disp(y);

That isn't a function at all, but a script...
Wrap the computational part in a function to be called and name it something appropriate--*sincos* might suit... :)

function sincos()
b = input('Enter the angle value in radians: ');
x=sin(b); y=cos(b);
fprintf('The sin of value %f is %f\n',b,x);
fprintf('The cos of value %f is %f\n',b,y);

@Dr. Siva Srinivas Kolukula: Note that it is much more robust and secure to call input with its 's' option to return a string, this prevents evaluation of any arbitrary code that a user might enter, or from throwing unnecessary errors:
b = str2double(input('Enter the angle value in radians: ','s'));

I speculate that the assignment is requesting that you build a series or taylor expansion that calculates sin and cos both.
