IsTangent

  

test if a plane is tangent to a sphere

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

IsTangent(p, s)

Parameters

p

-

plane

s

-

sphere

Description

• 

The routine returns true if the plane p is tangent to the sphere s; false if they are not; and FAIL if it is unable to reach a conclusion.

• 

In case of FAIL, if the third optional argument is given, the condition that makes p tangent to s is assigned to this argument.

• 

The command with(geom3d,IsTangent) allows the use of the abbreviated form of this command.

Examples

(1)

Find the condition that makes the plane  tangent to the sphere s

(2)

IsTangent:   "unable to determine if 1-abs(c+d)/(a^2+b^2+c^2)^(1/2) is zero"

(3)

Hence, the condition is:
