(c) calculate the true derivative j'(x analytically. evaluate at 1 (d) approximate using the definition of the derivative you derived in problem 3.b. and the range of step sizes, h, defined above to. make use of your anonymous function in order to do this. if you run your code without using a loop, matlab will throw an error. how can you fix the delinition of the anonyimous function so that you don't need to use a loop? write your answer. calculate the relative error of your approximation of the derivative. use the note in hw3 problem 3 if you need .
