Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: A given family of curves is said to be 'self - orthogonal’ if the family of orthogonal trajectory is the same as the given family of curves
Reason R : For finding orthogonal trajectory, replace \(\rm \frac{dy}{dx}by-\frac{dx}{dy}in \ f\left(x, y, \frac{dy}{dx}\right)=0\)
In the light of the above statements, choose the correct answer from the options given below
1
Both A and R are true and R is the correct explanation of A
2
Both A and R are true but R is NOT the correct explanation of A
3
A is true but R is false
4
A is false but R is true
