What does it mean if the first and second derivative are positive?

Graphically, the first derivative gives the slope of the graph at a point. The second derivative tells whether the curve is concave up or concave down at that point. If the second derivative is positive at a point, the graph is bending upwards at that point.

Why would you use the second derivative test?

The second derivative may be used to determine local extrema of a function under certain conditions. If a function has a critical point for which f′(x) = 0 and the second derivative is positive at this point, then f has a local minimum here. This technique is called Second Derivative Test for Local Extrema.

What happens when second derivative is positive?

The positive second derivative at x tells us that the derivative of f(x) is increasing at that point and, graphically, that the curve of the graph is concave up at that point. So, if x is a critical point of f(x) and the second derivative of f(x) is positive, then x is a local minimum of f(x).

What does first derivative test tell you?

The first derivative test is the process of analyzing functions using their first derivatives in order to find their extremum point. What if we told you that given the equation of the function, you can find all of its maximum and minimum points? Well, it’s true! This process is called the first derivative test.

Is the integral of the second derivative the first derivative?

The integral of a derivative would be up to some constant, the function itself”. To call something a second derivative is, in this circumstance, superficial since that second derivative can be written as the first derivative of some other function (namely, the first derivative of the original).

How do you get in touch with your intuition?

They take time for solitude. If you want to get in touch with your intuition, a little time alone may be the most effective way. Just as solitude can help give rise to creative thinking, it can also help us connect to our deepest inner wisdom. Intuitive people are often introverted, according to Burnham.

Do you know how to think about derivative?

Maybe you aren’t aware of it, but you already have an intuitive notion of the concept of “derivative”. You probably use it almost everyday. The word “derivative” doesn’t serve as a very good description of it, I think. Basically, there are two ways of thinking about the derivative of a function. The first way is as an instantaneous rate of change.

What is the first and second derivative of a function?

If our function is the position of , x, then the first derivative is the rate of change or the velocity of . f ( x). The second derivative is acceleration or how fast velocity changes. Graphically, the first derivative gives the slope of the graph at a point.

Can you train your intuition to be more creative?

In fact, creative people are highly intuitive, explains Burnham, and just as you can increase your creativity through practice, you can boost your intuition. In fact, practicing one may build up the other.
