Homework Help: Calculus (Normal Line, please check my work)

Posted by Mishaka on Saturday, December 17, 2011 at 3:51pm.

The slope of the line normal to the graph of 4 sin x + 9 cos y = 9 at the point (pi, 0) is:
Derivative: 4cosx - 9siny(dy/dx) = 0
(dy/dx) = (-4cosx) / (-9siny)
(dy/dx) = (4) / 0
Normal line = -1 / (4/0)
Does this mean that the slope of the normal line is undefined, or did I do my calculations incorrectly???
