ap, calculus, slope field


3. dy/dx = (x + 1)2y
Let y = f(x) be the solution of this equation with the initial condition f(1) = 1. What is the equation of the tangent to the graph of f at x = 1?


4. dy/dx = (x + 1)2y
Find the solution y = f(x) to the given differential equation with the initial condition f(1) = 1.


5. Consider the closed curve in the xy plane given by 2x2 + 5x + y3 + 4y2 + y = 8.
Show that dy/dx = -(4x + 5)/(3y2 + 8y + 1).


6.

The graph of function f is shown above. Let:

Calculate g(3). Does g have a relative minimum or a relative maximum at x = -1? Calculate g"(0).


7. Let f be the function given by f(x) = (2x2 + 5x -1)7.
Write the equation for the line tangent to f(x) in x = 0.


8. Find the coordinates of the two points on the x2 - 2x + 4y2 + 16y + 1 = 0 closed curve where the line tangent to the curve is vertical.
