Hello, I'm having trouble with a very simple program. I want it to approximate a square root of a number R. So here is my program : For example, if you enter R as 3, a as 1, b as 2 and Tol as 0.001, it should return " d " as the square root of we were looking for, "i" as the number of steps to reach it, and "f(d)" as the real value of the function f (obviously close to Tol). But it doesn't work. I've tried to find an error, but I don't see any. Maybe there is a problem in the function f.... but I'm not sure. I'd be grateful if you could run the program to see what happens, or if you any error. Thanks a lot.
