Find the values of θ and p, if the equation x cos θ + y sin θ = p is the normal form of the line .

Given: The normal form of the line .

To find:

Value of θ and p.

Explanation:

Divide Both side by 2

Comparing the equations xcos θ + ysin θ = p we get,

cos θ, sin θ and p = 1

∴ θ = 210∘ and p = 1

Hence, θ = 210∘ and p = 1
