Variables Used:
X , Y , Z The rectangular components of v
U , V , W The rectangular components of v
R , T , P The radius, the angle in the x – y plane ( ), and the angle from
the Z axis o f v
D The dot product
G The angle between vectors ( )
Example 1:
A microwave antenna is to be pointed at a transmitter which is 15.7 kilometers
North, 7.3 kilometers East and 0.76 kilometers below. Use the rectangular to
polar conversion capability to find the total distance and the direction to the
transmitter.
