Expert Answer

Step 1

Firstly, we find  dy/dx by differentiating both sides with respect to x

Step 2

We know that slope of tangent(m1) to curve at point (x1,y1) is the value of dy/dx at (x1,y1) and the we find the equation of tangent at (x1,y1) by using formula shown on board.

Step 3

Now we know that tangent and normal are perpendicular, So the product of their slopes is -1,Since, slope of tan...
