Thu 3 Apr, 2014 06:26 am - Thanx Everybody, My doubt is clear now. Just like First derivative Test tells us the behaviour of the function whether it is increasing or decreasing. The Second Derivative Test tells us the... (view)
Wed 2 Apr, 2014 03:45 am - I understand the 1st derivative test for testing concavity which says
The graph of a differentiable function y=f(x) is
1. concave up on an interval I if f' is increasing on I.

Wed 2 Apr, 2014 02:43 am - Hello fresco,
I understood my misconception about the quadratic curves. Quadratic curves are parabola which has to be symmetric about its "Axis of Symmetry". And as the graph under... (view)
Tue 1 Apr, 2014 09:07 am - Hello fresco, how u are saying the function f is not quadratic (bounded by green vertical lines). It is clearly visible its a parabola so its derivative must be linear. Any curve appearing like a... (view)
Tue 1 Apr, 2014 01:44 am - Hello friends,
I'm trying to understand Concavity, But I've some doubts. As we know quadratic polynomial on graphing forms a parabola opening upwards or downwards. While understanding... (view)
