There are 18, 267 heart disease death cases with an average of 50 deaths per day. You are given a task to predict the voltage produced by a device that regulates any slow or irregular heartbeats after it is implanted into the body. Develop a suitable differential equation model to represent the voltage over time.

a) By using THREE (3) numerical methods, estimate the voltage obtained.

b) Based on your results in question a) above, prepare report. The report should elaborate on the most accurate method based on error analysis, by stating all the assumptions used in the development of model.
