	A tangent to a curve through a point not on the curve		2008-07-23
		Carter pose la question : How does one find the tangent points on a curve, given only the curve's function and the x-intercept of that tangent line? i.e. Find the point(s) on the curve y = -(x^2) + 1, where the tangent line passes through the point (2, 0). I know that there will be two such points, one where y is very close to 1, and the other point where y is a large negative number. However, I do not recall how to figure out the tangent line equation given a single intercept and solving to find the tangent points. Penny Nom lui répond.
