Problem meant to be solved in matlab

00 nitx f(x) sin n n=1,3,5... (478) TT Note that in this series n is only odd integers (n=1,3,5...) A finite series fm(x) may be evaluated to as many terms as you choose; more terms will give a more accurate reproduction of f(x). Here m corresponds to the largest value of n in the series. So, for example, f(x) has three terms corresponding to n = 1, 3 and 5. a. Plot one period of the square wave for your choice of L (but be sure to define L clearly in the comments). Use a black line, no markers. b. Overlay at least three plots fm with different m (e.g. m=1, 5 and 11). Use a different color line for each, no markers. Add a legend. c. Evaluate the error at x=L/2, defined as: error = abs ( f(L/2) - fm(L/2)) What m is needed to achieve error
