Please show exactly how it is in MATLAB

The cosine function can be evaluated by the following infinite series: cos = 1 ^2/ 2! + ^4/ 4! ^6 /6! + Create an M-file to compute cos(1.2345 rad) for up to and including eight terms, which is up to the term x^14/14!.

a) Your program should compute and display the values of cos as each term in the series is added, e.g.

cos = 1

cos = 1 ^2/ 2!

cos = 1 ^2 /2! + ^4/ 4!

b) Compute and display the true relative error as a percentage = true valueseries approximation true value 100%
