Homework Statement
The normal to the curve y= (x + 2)^2 at the point A(-3, 1) meets the curve at B.
Find the angle at B between the curve and chord AB.
2. The attempt at a solution
I found that B is (-0.5, 2.25) and the equation of the normal is 2y= x + 5.
I thought the angle at B between the curve and chord AB was simply the angle between the normal 2y= x + 5 and the gradient function, y'= 2x +4 but the answer is different from what I get.
Any help would be greatful
