5. Any vector can be written as a linear combination of two standard unit vectors. The vector v is a linear combination of the vectors i and j. The scalar a is the horizontal component of v and the scalar b is the vertical component of v.

6. We can describe the position of a moving particle by a vector, r ( t ). If we separate r ( t ) into horizontal and vertical components, we can express r ( t ) as a linear combination of standard unit vectors i and j.

7. In three dimensions the component form becomes:

10. Most of the rules for the calculus of vectors are the same as we have used, except: “Absolute value” means “distance from the origin” so we must use the Pythagorean theorem.

11. Example 5: a) Find the velocity and acceleration vectors. b) Find the velocity, acceleration, speed and direction of motion at.

12. Example 5: b) Find the velocity, acceleration, speed and direction of motion at. velocity: acceleration:

13. Example 5: b) Find the velocity, acceleration, speed and direction of motion at. speed: direction:

14. Example 6: a) Write the equation of the tangent where. At : position: slope: tangent:

15. The horizontal component of the velocity is. Example 6: b) Find the coordinates of each point on the path where the horizontal component of the velocity is 0. 
