u To draw and analyze the asymptotes

[G-SLV]-[ASYM]

Example

To draw the asymptotes for the hyperbola

Use the following V-Window settings.

Xmin = –6.3, Xmax = 6.3, Xscale = 1

Ymin = –5,

Ymax = 5,

Yscale = 1

To determine the eccentricity of the graph for ellipse

Use the following V-Window settings.

Xmin = –3,

Xmax = 7,

Xscale = 1

# Certain V-Window parameters can produce

errors in values produced as graph analysis
results.

# The message ”Not Found” appears on the

display when graph analysis is unable to
produce a result.

# The following can result in inaccurate analysis

results or may even make it impossible to obtain a
solution at all.

- When the solution is tangent to the

x

-axis.

- When the solution is a point of tangency

between two graphs.
