Question

CONDITIONS OF TANGENCY OF A LINE TO A CURVE OF ANY POSITIVE INTEGRAL DEGREE IN X

Answer 1

Answer:

The normal line to a curve at a particular point is the line through that point and perpendicular to the tangent. ... Thus, just changing this aspect of the equation for the tangent line, we can say generally that the equation of the normal line to the graph of f at (xo,f(xo)) is y−f(xo)=−1f′(xo)(x−xo).
