shortest distance?? 1. The problem statement, all variables and given/known data find the shortest distance of y=x^2 from (4,0) 2. Relevant equations 3. The attempt at a solution if y=x^2, then y'=2x where x=4 the slope is 8 the solution is y=8(x-4) if that is the tangent line \, the normal line would be y=(1/8)(x-4) after that.. i'm stuck!!
