السلام عليكم يا اخوان انا عجزت بمعنى الكلمة وما خليت احد انه يساعدني ومافي فايدة ابي احد يساعدني باسئلة الرياضيات لا هنتم
Question-1: (15 marks)
Let f(x) be a polynomial of degree 3 which has a critical point at and an inflexion point at .
(6 points) Determine f(x) .
(2 points) Find another critical point of f(x) (if any).
( 4 points ) Determine the intervals where f(x) is increasing and where it is
decreasing .
( 3 points ) Use the first derivative test to find the local extrema of f(x)
__________________________________________________ ___
Question-2: (15 marks)
Consider the function
( 5 points ) Find the equation of the line normal to the graph of f(x) when .
( 5 points ) Find the x coordinates of the points on the graph of f(x) where the tangent to the graph is horizontal.
( 5 points ) Find the absolute extrema of the function on the interval [-2,2] .
__________________________________________________ ___
Question-3: (15 marks) Consider the two parabolas : and
( 4 points) Find the points of intersection of the parabolas and decide which one is greater than the other between the intersection points.
( 4 points ) Compute the area enclosed by the two parabolas.
( 3 points ) Use Mathcad to draw the graphs of the parabolas and find their intersection points graphically .
( 4 points ) Solve the differential equation
.
