I need assistance creating a separate project M file for each of the 4 functions below. do not try and find matlab functions which do these things for you, i am attempting to practice using simple code. the functions should print nothing (no disp and please use semicolons to suppress calculation outputs) only return the value requested.

Thank you!

The Function M-Files: 1. mypiecewise (a,b) which takes two inputs: a: A real number. b: A real number. Does: o If a. b return sin (a), assume a. is in radians. Returns: As above. 2. myfunctionsumtf ,m,d) which takes three inputs: 1?: A function handle. m: A real number. (1: A real number. Does: Calculates the sum mf(m) + (m + d)f(m + d) + (m + 2d)f(m + 2d)... + (m + 38d)f(m + 38d). Returns: This sum. 3. myfunctionchecktf ,a,d,M) which takes four inputs: :f: A function handle. a: A real number. (1: A real number. M: A real number. Note: You may assume that f (a) a. Does: Checks f(m) for a: = a, a: = 0,9- d, a: : (5+ 2d, a: = a + 3d, until f(m) Z M. Returns: The rst xvalue checked satisfying f(;c) 2 M. 4. myimproperintegral(f,b,t) which takes four inputs: 1': A function handle. b: A real number. 1:: A real number. Note: You may assume that f (0) is undened but that the imprOper integral f; f(:i:)d:1: exists. You may also assume I) > % Does: Calculates b b :5 f( mm, \"mm, f(a:)da:,... 21) (23) (23) until successive integrals differ by less than 1;. Returns: The nal calculated integral
