Use Mat Lab to solve this please post code:

Consider f(x) = ex sin(x) + cos(x). Write a MATLAB script file to do the following: A. Express each of the 3 elementary functions of f (x) as polynomial coefficient vectors B. Use built-in functions/operators to combine the 3 vectors into 1 polynomial C. Use built-in functions that operate on polynomial coefficient vectors to find f (1), based on their Maclaurin series expansions. For each elementary function, include the first 4 terms of its series expansion in its polynomial coefficient vector coefficient vector that approximates f (x). Hint: You will need to with 0s on the left. pad one vector /"(0.3), and /o)x Hint: Use the fundamental theorem of calculus to helyp evaluate the definite integral. D. Compute the same values as the previous subpart using functions of the Symbolic Toolbox
