#representing vectors
lime ibex
i have done 2+3λ and 5-λ but idk what to do next
If its parallel to i then it is horizontal so the j component wont be increasing or decreasing
5-lambda= 0
Lambda=5
If you sub lambda=5 into it you get 17i + 0j if you draw that you can see its horizontal

so what is the vector i
like is there a column vector for it
i have done 2+3λ = i and 5-λ = j
lime ibex
so what is the vector i
i is just the x axis
If a question says its parallel to i its parallel to the x axis
You can’t just set it equal to i though
Parallel is not the same as equal

If you sub lambda=5 into it you get 17i + 0j if you draw that you can see its ho...
Like how I worked it out here to be 17i
17i is parallel to i but not equal
lime ibex
the vector is 17 units in the x axis?
Yes

thank you
makes a lot more sense now
i was thinking i meant a value this entire time
