Q2 of 85 Page 233

Find the values of q and p, if the equation x is the normal form of the line .

The equation of the given line is

This equation can be reduced as



⇒


On dividing both sides , we obtain,



…………….(1)


On comparing equation (1) with xcosƟ + ysinƟ = p, we get,


cosƟ = and sinƟ = and p = 1


Since, the value of sinƟ and cosƟ are negative,



Therefore, the respective values of Ɵ and p are and 1.
