Definitions of tangent and normal, finding tangent and normal lines to a function
L:mx+c is tangent to f(x) at x=a means
Using point slope form the equation of the tangent is:
The normal to f(x) at x=a is the line that passes through (a,f(a)) and is perpendicular to the tangent:
Using point slope form the equation of the tangent is:
