Hi guys, can some one help me to solve my problem?
i've be facing difficulty to find the number of function evaluation. let's say that i have f(x)=x^3+x^2-2 with initial value of x(0)=1.5
i want to calculate x(n+1)=x(n)-(f(x(n)/fprime(x(n))) until n=5
thus, i want to calculate how many time of f(x(n)) have been use until n=5. but if the first iteration has use f(x(1)) then the second iteration also use f(x(1)), it is considered as we only use f(x(1)) one time only.
can someone help me
