Question

3) Find the ear of tangent to the
curve y=x²-22-3 where it meets
the axis​

Answer 1

Answer:

Since, t

1

and t

2

are end-points of focal chord

⇒t

1

t

2

=−1

or t

2

=−

t

1

1

.....(i)

Since, t

1

and t

2

are end-points of normal chord.

⇒t

2

=−t

1

−

t

1

2

......(ii)

From (i) and (ii)

−

t

1

1

=−t

1

−

t

1

2

⇒t

1

2

=−1

or t

1

=−i

So no such chord is possible.
