Normal at `(x_1, y_1)` and `(acostheta, b sin theta)`

If the focal chord of the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1, is normal at (a cos theta,b sin theta) then eccentricity of the ellipse is

The normal to the curve x=a(1+cos theta), y=a sin theta " at " 'theta ' always passes through the fixed point

The normal to the curve x=a(1+cos theta), y = a sin theta at 'theta' always passes through the fixed point :

The normal to the curve x = a (1+cos theta), y = a sin theta at theta always passes through the fixed point

The normal to the curve x=a(cos theta + theta sin theta), y=a(sin theta - theta cos theta) at any theta is such that

The normal to the curve x=a(cos theta + theta sin theta), y=a(sin theta - theta cos theta) at any theta is such that

The normal to the curve x=a(cos theta + theta sin theta), y=a(sin theta - theta cos theta) at any theta is such that
