Vectors
Length of a vector, which is denoted as |v|, and can be found using the distance formula
What is Magnitude?
The equation
x2 + y2 = r2
graphs this type of shape
What is a circle?
When using polar equations, you calculator needs to be in this mode
What is polar mode?
What is radian mode?
u = <3,5>
v = <-2, 3 >
u + v = ?
What is <1,8>?
This vector is found using the equation
u = v/ |v|
What is a unit vector?
This equation gives one of the variables of a parametric equation
(gravity)t2+(speed sin(x))t + initial height
What is y?
What is the height?
Using these equations, you are finding BLANK
(r, theta)
(r, theta + 2pi n)
(-r, theta + (2n+1) pi)
What are all polar coordinates?
The Mississippi river starts at this state park
What is Itasca?
This vector informs us of __________
v = <|v|cos(x), |v|sin(x) >
What is the direction angle?
What is the direction of the vector?
There are two ways to complete this process.
One way is to solve a system of equations.
The other is to square both equations, add them together, and then simplify, possibly using properties from your booklet
What is eliminating the parameter?
A plane with point 0 the pole and a ray
from 0
What is a coordinate plane?
This physics equation can be written as a vector in precalculus.
The vector's magnitude is the weight, and the vector's direction is given by the angle.
Name the operation
u . v = u1 v1+ u2v2
What is the dot product?
You are completing this process if, in a problem, you are given a line going through two points.
What is parametrization?
r = 2cosθ + 1
Find r when θ is π/2
What is 1?
This artist was a Dutch Baroque painter and printmaker born July 15, 1606, in Leiden, Netherland and died in poverty on October 4, 1669, in Amsterdam. He was known being painter of light and shade and as an artist who favoured an uncompromising realism
