Calculus geometry question

  1. Jan 8, 2008 #1
    1. The problem statement, all variables and given/known data

    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

    The angle your are looking is between the chord AB and the tangent of the curve at B.
