Analysis Results:

• The image contains handwritten mathematical expressions on grid paper.
• The visible expressions appear to be:
• A curve with what looks like a caret or a partial 'n' shape above it.
• Below the curve, on the left side, a character resembling 'n' followed by a colon and then '0.5'.
• Below that, another character resembling 'n' with a subscript or modifier, followed by a horizontal line and then '1'.
• On the right side, a similar character to the left, followed by a colon and then '0.5'.
• Below that, a character resembling 'n' with a subscript or modifier, followed by a horizontal line and then '2'.
• The grid lines suggest a structured layout, possibly for calculations or data plotting.
• The writing is in blue ink.
