#### The normal of the curve given by the equation x = a (sin + cos), y = a (sin – cos) at the point Q is -

Maths-General

- (x + y) cos + (x – y) sin = 0
- (x + y) cos + (x – y) sin = a
- (x + y) cos – (x – y) sin = 0
- (x + y) cos – (x – y) sin = a

#### Answer:The correct answer is: (x + y) cos – (x – y) sin = 0
