Finding the Normal to a Surface One of the elements of solving surface integrals in vector calculus is determining the normal to a surface so that we can evaluate the flux of a vector through that surface. We can write our surface as some function : f =f Hx, y, zL=c (1) where c is a constant. For example, the equation of a plane has the form :

Basic Principle: The slope of the normal line is the opposite reciprocal of the tangent line’s slope, because the normal line is perpendicular to the tangent line. This can also be described as the normal line is orthogonal to the curve. 1. Find the standard form of the equation of the tangent and the normal to the graph of y = x2 at the ...

The tangent is a straight line which just touches the curve at a given point. The normal is a straight line which is perpendicular to the tangent. To calculate the equations of these lines we shall make use of the fact that the equation of a straight line passing through the point with coordinates (x1,y1) and having gradient m is given by y − y1
