HI RUMMIES... ANY EDUCATIONAL MANAGEMENT HERE OR ANY EDUCATION HERE ?

Hi bro....just change my course 2 Educational Management....pleased 2 meet u.

thankyouJesus:
Good morning all, something hit me, nobody, I repeat nobody has ever ask a question from either differentiation and integration classes. I can't evaluate, re-strategise, e.t.c when there is no feeback (questions).
I want to slow down because of questions, am waiting.

pls can u shed more light on differentiation maximum n minimum value

pls can u shed more light on differentiation maximum n minimum value

in simple term,
if y = an expression
find the dy/dx, equate the dy/dx to 0, to get the values of x, substitute the values of x into the original question i.e y, if the answer is negative (max), if the answer positive (min)

thankyouJesus:

[b]Last aspect of differentiation for this class.
Differentiation Application (Maximum and Minimum values).
I hate stories when it comes to Mathematics, without wasting much time.
If y = x³/3 - x² - 2x + 5.
1. Stationary points are given by dy/dx = 0.
2. The type of each stationary point is determined by substituting the roots of the equation dy/dx = 0 in the expression for d²y/dx².
If y" is negative, then y is a maximum.
If y" is positive, then y is a minimum.
If y" is zero, then y may be a point of inflexion.
We shall need both the first and second derivatives, so make sure you are ready.
. . . . . . . . . . . . . . . . . . . . . . . .
Example 1: if y = x³/3 - x² - 2x + 5, then y' = . . . . . . . . .and y" = . . . . . . . .
Solution:
y = x³/3 - x² - 2x + 5.
.
.
.
.
.
.
.
y' = x² -x - 2.
y" = 2x - 1.
(a) Stationary points occur at y' = 0.
Therefore, x² - x - 2 = 0.
Therefore,
(x - 2) (x + 1) = 0.
Therefore,
x = 2 and x = -1.
i.e. stationary points occur at x = 2 and x = -1.
(b) To determine the type of each stationary point, substitute x = 2 and then x = -1 in the expression for y".
At x = 2, y" = 4 - 1 = 3, i.e positive, therefore, x = 2 gives y_min.
At x = -1, y" = -2 - 1 = -3, i.e negative, therefore x = -1 gives y_max.
To find the min and max values, substituting in y = f(x) gives x = 2,
y_min = 5/3
and x = -1,
y_max = 37/6.
. . . . . . . . . . . . . . . . . . . . . . . . Summary:
This is all about differentiation concerning JAMB syllabus, differentiation is a wide topic.

What kind of research is that?

UI has only conducted two PPTs (in 2013 and 2014) and you say they do repeat questions? You are a big time joker.
