Find the equations of the tangent and the normal to the given curve at

1.	Find the equations of the tangent and the normal to the given curve at the indicated point : `(x^(2))/(a^(2)) + (y^(2))/(b^(2)) = 1 " at " (a cos theta, b sin theta)`
Answer» Correct Answer - `b x cos theta + ay sin theta = ab, a x sec theta - by "cosec" theta = (a^(2) -b^(2))`
