So we have an infinite number of solutions. An initial value problem is then a differential equation (ordinary or partial, or even a system) which, besides of stating the relation among the derivatives, also, by giving the initial conditions, specifies the values of the unknowns at some point.
The function has a minimum value at x = a if f '(a) = 0 and f ''(a) = a positive number. The function has a maximum value at x = a if f '(a) = 0 and f ''(a) = a negative number. In the case of the maximum, the slope of the tangent is decreasing -- it is going from positive to negative.We can see that at the points C, A, D. Example 2.Let f (x) = 2 x 3 â 9 x 2 + 12 x â 3.- the critical values are x = a and x = b. The critical values determine turning points, at which the tangent is parallel to the x-axis. The critical values -- if any -- will be the solutions to f ' (x) = 0. Example 1. Let f (x) = x 2 â 6 x + 5.
