This work is solely my own origin. I affirm I am the student registered for and taking this homework. Misrepresentation is considered academic misconduct and may result in failure of the course and/or further disciplinary action, including dismissal from the University Signature without signature your HW may be discarded Student instructions: Solve the problems using Matlab. Put your result in the appropriate red box. Your script can be tested and your result verified. Not working program will not be grated. To get the result use copy-paste from Matlab editor and command window. Indicate only the final numerical result for variable required in the answer box. No any intermediate steps required. Manually written results will not be accepted. Submit your solution as a pdf file in Assignment link. Two attempts of submission are available. Ignoring the above instruction might result of discarding your work. HW#2 worth 20 points of your final grade. Submission file should be named as "Your Name_HW2 WI-20.pdf" Problem 1.
