Enter: int(x^2 + x, x, 1, 2)
Output: 26/3 = 3.8333… (correct)
Enter: 1 -> x
Enter: int(x^2 + x, x, 1, 2)
Output: 26/3 = 3.8333… (correct again)
Clear the value of x
Enter: int(x + 1/x, x, 1, 2)
Output: 3/2 +ln(2) \approx 2.193 (correct)
Enter: 1 -> x
Enter: int(x + 1/x, x, 1, 2)
Output: 10/3 = 3.333… (incorrect)
If the calculator is not ignoring the stored value of x in step 11, I would have expected the input to have been interpreted as int(1 + 1/1, x, 1, 2) which should produce 2 as the output.
