Here is the question:
I have posted a link there to this thread so the OP can see my work.An Hyperbola has the equation x^2/4 - y^2/9 = 1?
- Find the coordinates of the point on this curve with x=4, y>0
- Find the slope of the normal to the curve at this point, and hence find the equation of the normal. Give the equation in general form, ie. Ax+By+C=0
