(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 .

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
