Question

in matlab please and do not use while or for ty for your time

4. Write the function ExpSeries that will take a real number x as input, and return the result of the following summation: rrr? r? rº + + 0! 1!2! 3! 9! + + You can use the built-in function factorial. This series actually approximates the function et. You can check your function by comparing its result with that of the built- in function exp.

Answer 1

Code:

x = 1; % you can choose any

%value you like for x

exp_apprx = ExpSeries(x)

exp_true_val = exp(x)

%Your Function

function exp_apprx = ExpSeries(x)

num = 0:9;

den = factorial(0:9);

term = (x.^num)./den;

exp_apprx = sum(term);

end

Output:

x = 1; % you can choose any %value you like for x exp_apprx = ExpSeries(x) exp_true_val = exp(x) exp_apprx 2.7183 exp_true_val 2.7183 function exp_apprx = ExpSeries(x) num 0:9; den = factorial(0:9); term = (x.^num)./den; exp_apprx end sum(term);
