Use MATLAB fuctions to solve this

The Taylor series of exp (x) can be expanded as following e^x = Sigma^infinity_n = 1 x^n! = 1 + x/1! + x^2/2! + x^3/3!+... Task 1: Write a custom function to calculate exp(x) with the two input arguments are x and n (where n is the number of terms) and one output argument is the value of exp(x). Task 2: Use the function in task 1 to calculate exp(2) with 3 terms and exp(3) with 6 terms. Task 3: Calculate the error percentage between the result of exp(3) with 3 terms from task 2 and the result of exp(3) using the built-in exp() function in Matlab. If you want the error less than 0.001%, how many terms will be needed
