MATLAB: Write a function called e_to_the_x to estimate e^x using its Taylor series (sigma(x^n!) starting with n = 0, add terms until 2 subsequent approximations differ by less than 10^-6 using a while loop. (HINT: use the built-in function factorial))

Test with e_to_the_x(1) and e_to_the_x(-1)

Write a function called e_to_the_x to estimate e using its Taylor series n! starting with n -0, add terms until 2 subsequent approximations differ by less than 10-6 using a while loop. (HINT: use the built-in function factorial))
