Derivative of function is one of the topics in the mathematics book in Se- nior High School (SMA). In some textbooks used by students, there is no general form of the nth derivative of the function h(x)/f (x) or h(x)/√f (x). This thesis discusses how to obtain the general form of thenth derivative func- tion 1/(ax + b), (ax + b)/(cx + d), 1/√ax + b, and (ax + b)/√cx …
