Question 348281: The equation y = 0.5x - .01x^2 represents the parabolic flight of a certain cannonball shot at an angle of 26 degrees with the horizon and an initial velocity of 25 meters per second. In this equation, y is the height of the cannonball, in meters, and the x is the vertical distance traveled, in meters. Given the coordinates of (10,4) and (40,4) lie on the parabola, at what x-coordinate must the vertex lie?

Question 349347: When you use the chain rule to find the slope of a tangent line for the equation x^2+4y^2=4 at point (sqrt(2), -1/sqrt(2)) the slope comes out as m=-1/2 .
When you use implicit differentiation, however, the slope comes out as m=1/2 The back of my textbook states the answer as m=1/2.
Why is m=-1/2 not the correct slope and why does the chain rule give me that answer?
