can someone else please answer and include the actual steps on matlab for the entire problem, I have not used matlab before. How do you assign the error to variables, there is no command for +/-.

Problem 2 from the slides: You are measuring force using a load cell in isometric conditions and want to calculate the net moment of force at the elbow. What is the value and error of M in the following figure if: L (length of forearm) =30+/1cm (angle between axis of transducer and forearm) =602 FT (Force measured by transducer) ranges from 1 to 50N, with an error of 3N Plot the results in a line graph showing the error interval. In addition to the functions used in 1, the following Matlab functions may be helpful: figure; plot; legend
