Use MATLAB to show that the sum of the infinite series 12n=02n+1(3)n is equal to . Do this by computing the sum for: a. n=10 b. n=20 c. n=30 Follow these instructions to solve the problem i. For each part create a vector n in which the first element is 0 , the increment is 1 and the last term is 10,20 , or 30 , respectively. ii. Use element-by-element calculation to create a vector in which the elements are 2n+1(3)n. iii. Use the function sum to add the terms of the series and multiply the result by 12. The variable is res. iv. Compare the values obtained in each part to the actual value of using percent error. PE= Actualres-Actual100
