Shading Above and Below
When you select é or ê for two or more functions, the TI-84 Plus C rotates through four shading
patterns.
• Vertical lines shade the first function with a é or ê graph style.
• Horizontal lines shade the second.
• Negatively sloping diagonal lines shade the third.
• Positively sloping diagonal lines shade the fourth.
• The rotation returns to vertical lines for the fifth é or ê function, repeating the order described
above.
When shaded areas intersect, the patterns overlap.
