- Iteration[ <Function>, <Start Value>, <Number of Iterations> ]
- Iterates the function n times using the given start value.
- Example:After defining
f(x) = x^2the commandIteration[f, 3, 2]gives you the result (32)2 = 81.
- Example: repeated additionTo obtain the repeated addition of 7 to the number 3:Let
g(x) = x + 7, thenIteration[g, 3, 4]yields (((3+7) +7) +7) +7 = 31.
