Key Notes (1.3 Properties of Graphs and Functions):
Intervals of increase: Intervals of the domain were y values increase as x values increase.
Ex. 1: f(x)=2x, Interval of increase: x R (the entire domain)
Ex. 2: f(x) = x2, Interval of increase: x > 0

6.5 Vectors in R2 and R3
Algebraic Vectors - All vectors can be defined by an ordered pair on the x-y plane.
When the tail of a vector is placed at the origin the resulting vector, _ is the position vector.
Let u be a vector in the plane.
Draw u so
MCV 4U 7.1 Forces As Vectors
Force can be considered as something that either:
All objects will move if one or more forces are applied to it.
of resulting motion is a direct result of adding the
