True or False?

Answer 29

Question 30

The two (or three) real number values contained in a column matrix to represent a point specify an absolute location in space relative to the currentcoordinate frame.

True or False?

Answer 30

Question 31

The two (or three) real number values contained in a column matrix to represent a vector (in 2D or 3D) specify a displacement of a specific distance from an arbitrary point in an arbitrary direction.

True or False?

Answer 31

Question 32

With regard to a vector, in 2D, the two values contained in a column matrix represent the displacements along three orthogonal axes.

True or False?

Answer 32

Question 33

In the case of 2D, the length of the vector is the length of the hypotenuse of a right triangle formed by the x and y displacement values.

True or False?

Answer 33

Question 34

In 2D, the direction of a vector can be determined from the angle formed by the x-displacement and the line segment that represents the hypotenuse of aright triangle formed by the x, y, and z displacements.

True or False?

Answer 34
