Tangents are drawn from the origin to the curve

y = \cos \;x

. Their points of contact lie on

View answer and explanation

Correct option: C

{x^2}{y^2} = {x^2} - {y^2}

The correct answer is C (

{x^2}{y^2} = {x^2} - {y^2}

) because it represents the locus of the points of contact of tangents drawn from the origin to the curve

y = \cos x
