Question

derive the equestion of line in normal form​

Answer 1

Answer:

⇒ x + y = 7√2, which is the required equation. Note: (i) The equation of a, straight line in the form of x cos α + y sin α = p is called its normal form. (ii) In equation x cos α + y sin α = p, the value of p is always positive and 0 ≤ α≤ 360°.
