    1. 1. Vector equation of a line: = +If = , , , = , , , = , , ,then , , = + , + , +Parametric equation: = + , = + , = +symmetric equation: = =
    2. 2. Vector equation of a plane: ·( )=If = , , , = , , , = , , ,then: , , · , , =Scalar equation: ( )+ ( )+ ( )=Linear equation: + + + =
    3. 3. Distance from a point ( , , ) to a plane + + + = is given by: | + + + | = + +Ex: Find the distance between ( , , ) and + = .Ex: Find the distance between the two planes + = , + = .
    4. 4. 13.1 Vector Functions and Space CurvesA 3D space curve can be represented by theparametric equations = ( ), = ( ), = ()It can be written as a vector function: ()= ( ), ( ), ( ) = ( ) + ( ) + ( )Ex: ()= , ( ),
    5. 5. Ex: ()= , ,
    6. 6. Ex: ()= ( + ) ,( + ) ,
    7. 7. Ex: ()= ( + . ) ,( + . ) , .
    8. 8. 13.2 Derivatives andIntegrals of Vec. Func.Definition of the derivative of a vector function: ( + ) () ()= ()= =If ()= ( ), ( ), ( ) = ( ) + ( ) + ( )then ()= ( ), ( ), ( ) = ( ) + () + ()
    9. 9. Differentiation Rules: ( ( ) + ( )) = ( )+ ( ) ( ( )) = () ( ( ) ( )) = ( ) ( ) + ( ) ( ) ( ( ) · ( )) = ( )· ( )+ ( )· ( ) ( () ( )) = () ( )+ ( ) () ( ( ( ))) = ( ) ( ( ))
