Hey guys, I have a little problem with an calculus question here:
Q: The gradient of the normal of a curve is given as (x-1)/(y-1). Find the equation of the curve if it passes through the point (2,2).
Now I know that the gradient of the curve is -(y-1)/(x-2), but how do I integrate this since it involve 2 variables? I'm thinking that this question might be a pure differentiation question in which I just need to manipulate the variable to make y the subject. But how?
