Reduce the equation x + y - 
= 0 to the normal form x cos ∝ + y sin ∝ = p, and hence find the values of ∝ and p.
Given equation is 
= 0
If the equation is in the form of ax + by = c, to get into the normal form, we should divide it by 
, so now
Divide by 
This is in the form of 
And
Conclusion: 
and p =1
