Plot this on the Cartesian Graph:

Determine the abcissa for (5,30)

Abcissa = absolute value of x-value
Perpendicular distance to the y-axis
Abcissa = |5| = 5

Determine the ordinate for (5,30)

Ordinate = absolute value of y-value

Evaluate the ordered pair (5,30)

We start at the coordinates (0,0)
Since our x coordinate of 5 is positive
We move up on the graph 5 space(s)

We move right on the graph 30 space(s)

Determine the quadrant for (5,30)

Since 5>0 and 30>0

Convert the point (5,30°) from
polar to Cartesian

The formula for this is below:

Polar Coordinates are (r,θ)
Cartesian Coordinates are (x,y)
Polar to Cartesian Transformation is
(r,θ) → (x,y) = (rcosθ,rsinθ)
(r,θ) = (5,30°)
(rcosθ,rsinθ) = (5cos(30),5sin(30))
(rcosθ,rsinθ) = (5(0.86602540408359),5(0.49999999948186))
(rcosθ,rsinθ) = (4.3301,2.5)
(5,30°) = (4.3301,2.5)

Determine the quadrant for (4.3301,2.5)

Since 4.3301>0 and 2.5>0
(4.3301,2.5) is in Quadrant I

Convert (5,30) to polar

Cartesian Coordinates are denoted as (x,y)
Polar Coordinates are denoted as (r,θ)
(x,y) = (5,30)

Transform r:

r = ±√x2 + y2
r = ±√52 + 302
r = ±√25 + 900
r = ±√925
r = ±30.413812651491

Transform θ

θ = tan-1(y/x)
θ = tan-1(30/5)
θ = tan-1(6)
θradians = 1.4056476493803

Convert our angle to degrees

Angle in Degrees  =  Angle in Radians * 180
  π

θdegrees  =  1.4056476493803 * 180
  π

θdegrees  =  253.01657688845
  π

θdegrees = 80.54°
Therefore, (5,30) = (30.413812651491,80.54°)

Determine the quadrant for (5,30)

Since 5>0 and 30>0

The formula for rotating a point 90° is:

R180°(5, 30) = (-5, -30)

Take (5, 30) and rotate 270 degrees
We call this R270°

The formula for rotating a point 270° is:
R270°(x, y) = (y, -x)
R270°(5, 30) = (30, -(5))
R270°(5, 30) = (30, -5)

Take (5, 30) and reflect over the origin

Formula for reflecting over the y-axis is:
