The partial output of the program shown below shows that the sign of the difference between the two sides changes between x=1.341627718511 and x=1.341627718512. Judging by the sizes of the differences from zero one would assume the answer is closer to the former number than the latter.
The code portion shown is the result of successive restrictions on the range and precision of the x values:
For x = 1.3416277185 To 1.3416277186 Step 0.000000000001
y = Sin(x) - Sin(x * x)
Text1.Text = Text1.Text & x & " " & Str(y) & crlf
