How to ... Flashcards
How would you calculate
Add the top numbers together, and add the bottom numbers together
How would you calculate
Multiply both numbers inside the vector by the number outside
How can you tell if two vectors are parallel
If vectors are parallel then they are scalar multiples of the same base vector
(you can multiply one by a scalar to make the other)
How would you find the magnitude of a vector
Use Pythagoras to find the length of the vector
(this works as you have two sides of the triangle)
How would you get from A to B?
What would the vector be for AB?
AO is a negative a because it is going against the arrow, the opposite way
How would you find the vector OM
(M is the midpoint)
How do you know if two vectors are the same
Vectors are the same if they have the same direction and magnitude
What changes when you make a negative vector
A negative vector has the same magnitude but is the opposite direction
What effect do scalars have on vectors
Multiplying a vector by a scalar can make it longer, or shorter if a fraction is used
Scalars change magnitude
How can you tell if two vectors are parallel
Two vectors are parallel if one is a multiple of the other
How would you find the column vector for
Count the squares across for the top number
Count the squares up for the bottom number
