Convert the Cartesian equation x - 5 = 0 to a polar equation.
mylen [45]

Answer:

  r = 5sec(θ)

Step-by-step explanation:

The usual conversion is ...

  y = r·sin(θ)

  x = r·cos(θ)

__

The second of these can be used here.

  r·cos(θ) -5 = 0

  r·cos(θ) = 5

  r = 5/cos(θ) = 5sec(θ)

A suitable polar equation is ...

  r = 5sec(θ)
