In Matlab Code:

Problem 3: Suppose a2.4T sin(0.1), b cos(0.2), c [4.5.2.4.2.0.8.1.-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) sin(ac-bd) 3.1) xsin(ac bd) cos(ab +cd) 3.2) y-ed?+cos(ab +cd) 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. 201. Note that element-by-element operation is needed. (10pts) x +2 x3-20x-28, x
