Please code in MATLAB and explain how it works so that way I can do this with different numbers. The correct answer for each problem is at the bottom of each question. I would like to understand how to get these correct answers. Thank you.

This assignment deals with determining the round-off error in a function of two variables due to errors in the independent variables.

If x=3.6 has an error of x=0.0900 and y=1.6 has an error of y=0.0090 and if z=1.0x4y2, what is z ? 47.8355 (with margin: 0.0001) If x=1.5 has an error of x=0.0020 and y=4.8 has an error of y=0.0003 and if z=4.6x4y4, what is z ? 69.021 (with margin: 0.0001) If x=1.3 has an error of x=0.0080 and y=0.1 has an error of y=0.0006 and if z=1.9cos(0.3x)cos(2.8y), what is z ? 0.0025 (with margin: 0.0001) If x=0.4 has an error of x=0.0070 and y=4.7 has an error of y=0.0002 and if z=4.5e2.2ycos(2.8x), what is z ? 2,483.4656 (with margin: 0.0001)
