!1 (TRCE)
Moving the cursor to the apex of the curve reveals that y =
50 (the maximum value) when x = 5.
This exercise shows that the cross-sectional area depends on where the sheet metal is bent.
You can determine the best location for the bends by observing where on the X-axis the
maximum value of Y is reached.
Check the x and y range settings before performing the operation.
