Problem 3. Suppose a = 2.4m + sin(0.1), b = cos(0.2), c = [452.4.208.1.-3.3.5.2.6], and d T,7.4,8,6.2.6,-3,5.3]. Do the following element-by-element assignments. (10pts) 3.1) x sin(ac-bd) cos(ab + cd) sin ac-bd) Problem 4: Write a code in m file that defines the piecewise force obtained from a statics problem given below. Evaluate the force for x = [-20.-5.. 2.20]. Note that element-by-element operation is needed. (10pts) x 2 x2-28 100x 503, 5s x
