Problem 8.13,8.14 8.13 The inverse sine (asin) and inverse cosine (acos) functions are valid onlfor inputs between 1 and +1, because both the sine and the cosine haveresult of asin or acos for a value outside the range as a complex numbervalues only between - 1 and +1 (see Figure P8.13).

The first problem, 8.13, requires a matlab function. A matlab function must be saved as a *.m file with the same file name as the function name. For example, my_asin(x) function should be saved as my_asin.m in order for matlab to recognise it as a function file. The second problem can be executed as a matlab script either from the command window or as a saved script file.Here is the required matlab code: function my_asin(x) if (x >= -1 && x <= 1) %Find asin(x) if -1 <= x <= 1 fprintf('asin (%.4f) = %.4f\n',x,asin(x)) else % Throw an error when x is out of range. error('Error. \n Input must be in the range -1 <= x <= 1.') endend Call the function from the command window. For example, type my_asin(1) in the command window and press enter. Here is the screenshot of the matlab window with some example commands: (Note: The last line is cut-off in the image, but most part of the question is visible. If there is any important information missing from the question image, please resubmit the problem 8.14 again with the complete question visible.) Here is the required matlab code: prompt = "Enter the outside air temperature in °F (as a scalar value): ";f = input(prompt);if f >= 80 fprintf('Wear shorts.\n')elseif (f > 60 && f < 80) fprintf('It is a beautiful day.\n')else %Here one can also write elseif f <= 60, but unnecessary. fprintf('Wear a jacket or coat.\n')end Run the scrip by pressing F5 or from the menu Editor-->Run. Here is a demo with some random values testing all 3 cases.
