Q6 of 319 Page 24

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
