9)component and vectors
-
subsitute <lvlcos(x),lvlsin(x)> where x=theta

8)linear combination
the outcome will not have the brackets of the vector, but instead will be written as xi+yj
-
-
11)dot product
v1.v2=<a1,b1>.<a2,b2>=a1.a2+b1.b2

13)vector projection
-
if the angle between the two vectors was acute, the projection will be projected normally, but if the angle was obtuse, it will be projected on the extension of the vector v
3)rectangular components
create a right triangle, and use sin, cos, or tan to find the angle
