Now you see why UI brutally increases cut-off mark?

They are tired of accommodating dull people

Such as this one.

thankyouJesus:
I must have been a pain in the ....... I am sorry, considering the fact that 5 shares elude us, no more mathematics class, but one thing I would't stop doing is, answering your mathematics question.
At this point, if you have any mathematics question(s), ask and I will do justice to them.
See you all in UI, I am sorry for all the trouble.

[b]Good evening ladies and gentlemen. Please, bear with us, we are sorry for the "Orubebe" (disturbing this thread with mathematics), if not, we will "Oba Akiolu" you.
FUNCTIONS OF A LINEAR FUNCTION OF X.
It is often neccessary to integrate any one of the expressions shown in our list of standard integrals (the note in the previous class) when the variable x is replaced by a linear expression in x. That is, of the form ax + b.
Note:
1. [size=40]$[/size](2x + 6)^n>1 dx the 2x +6 is a linear expression because the degree power of x is 1 and algebraic substitution is adopted.
2. [size=40]$[/size]cos(5x + 6) dx, the 5x + 6 is linear, therefore algebraic substitution is adopted.
3. [size=40]$[/size]e^{(8x + 7)} dx, 8x + 7 is linear, algebraic substition method.
4. [size=40]$[/size](2x² + 3)³ dx, the degree of x is 2, this is not linear but quadractic expression, to solve this, the brackets is expanded, the result will yield polynomials, integrate in turns.
5a. [size=40]$[/size](x sinx) dx, they are both linear expressions but they are connected together by multiplication, algebraic method would't work (we will consider a question like this in a later class).
5b. [size=40]$[/size]{(2x + 6)(x² + 6x)} dx, algebraic method can solve this, till later class..
In summary, algebraic substitution method is used to solve linear expression, but there are some special cases where it work also, it is all about substituting.
. . . . . . . . . . . . . . . . . . . . . . . .
Example 1: evaluate [size=40]$[/size](2x + 7)⁴ dx.
Solution:
[size=40]$[/size](2x + 7)⁴ dx
let u = 2x + 7,
differentiate u wrt x
du/dx = 2
making dx the subject of the relation
dx = du/2
substituting all the above into the question
=[size=40]$[/size]u⁴ du/2
1/2[u⁴⁺¹/4+1] + c
=1/2[u⁵/5] + c
=1/10[u⁵] + c
=u⁵/10 + c,
substituting back
=(2x + 7)⁵/10 + c
. . . . . . . . . . . . . . . . . . . . . . . .
Example 2: evaluate [size=40]$[/size]cos(2x + 7) dx.
Solution:
[size=40]$[/size]cos(2x + 7) dx
let u = 2x + 7
dx = du/2

[size=40]$[/size]cos(2x + 7) dx
=[size=40]$[/size]cosu du/2.
Note: cos is a standard integral (note of the previous class), integral of cos is sin.
= 1/2[sinu] + c
= sinu/2 + c
= [sin(2x + 7)]/2 + c.
. . . . . . . . . . . . . . . . . . . . . . . .
Example 3: evaluate [size=40]$[/size]e^{(2x + 4)} dx.
Solution:
[size=40]$[/size]e^{(2x + 4)} dx
let u = 2x + 4
dx = du/2
[size=40]$[/size]e^{(2x + 4)} dx
= [size=40]$[/size]e^u du/2
recall that e is also standard integral
= e^u/2 + c
= e^{(2x + 4)}/2 + c
. . . . . . . . . . . . . . . . . . . . . . . .
Summary:
Integration is easy if only you can understand differentiation.
. . . . . . . . . . . . . . . . . . . . . . . .
Assignment:
Practise the above, if you can the master the above, concerning JAMB/POST UTME, integration will be a walk over, only if you can master this.
. . . . . . . . . . . . . . . . . . . . . . . .
Any question?

. . . . . . . . . . . . . . . . . . . . . . . .
To all those we are stepping on their toes, we are deeply very sorry, dont "Orubebe" us so we would't "Oba Akinolu" you.
. . . . . . . . . . . . . . . . . . . . . . . .
Good Night.

[b]Good afternoon ladies and gentlemen, how is your day going?
INTEGRALS OF THE FORM [size=40]$[/size]f(x)f'(x) dx.
Consider the integral [size=40]$[/size]sinx cosx dx. This is not one of our standard integrals, so how shall we tackle it? This is an example of a type of integral which is very easy to deal with but which depends largely on how keen your wits are. You will notice that if we differentiate one of the two, we obtain the other expression.
. . . . . . . . . . . . . . . . . . . . . . . .
Note 1: Whenever you have integral of two products, the first thing is, can I differentiate to cancel out the other? If yes, algebraic substitution method is adopted:
. . . . . . . . . . . . . . . . . . . . . . . .
Example 1: evaluate [size=40]$[/size]sinx cosx dx.
Solution:
[size=40]$[/size]sinx cosx dx.
This is product of two expressions (sinx and cosx), since the differentiation of sin is cos and the differentiation of cos is -sin, therefore, I can pick any one of the two.
[size=40]$[/size]sinx cosx dx
let u = sinx
du/dx = cosx
dx = du/cosx
substituting back into the question
[size=40]$[/size]u cosx du/cosx
the cosx will strike out the other cosx, we are left with
[size=40]$[/size]u du
{u¹⁺¹/1+1} + c
u²/2 + c
sin²x/2 + c
. . . . . . . . . . . . . . . . . . . . . . . .
Example 2: evaluate [size=40]$[/size](2x + 3)(x² + 3x)² dx.
Solution:
[size=40]$[/size](2x + 3)(x² + 3x)² dx,
mere looking at the two shows that, if you differentiate the other without the power, you will get the other, so,
let u = x² + 3x
du/dx = 2x + 3
dx = du/(2x + 3)
substituting back
[size=40]$[/size](2x + 3)u² du/(2x + 3)
[size=40]$[/size]u²du
u³/3 + c
(2x + 3x)³/3 + c.
. . . . . . . . . . . . . . . . . . . . . . . .
Note 2: Can I manipulate to cancel out the other?
Example 1: evaluate [size=40]$[/size](x + 2)(x² + 4x)² dx.
Solution:
[size=40]$[/size](x + 2)(x² + 4x)² dx
mere looking shows that the other can strike out the other except that
.
.
.
.
.
.
.
Very good, multiply by 2.
[size=40]$[/size](x + 2)(x² + 4x)² dx
let u = x² + 4x
dx = du/(2x + 4)
[size=40]$[/size](x + 2)u² du/(2x + 4)
[size=40]$[/size](x + 2)u² du/{2(x + 2)}
[size=40]$[/size]u² du/2
[1/2(u³/3)] + c
u³/6 + c
(x² + 4x)³/6 + c
. . . . . . . . . . . . . . . . . . . . . . . .
Note 3: Is there a way I can go round?
Example 1: evaluate [size=40]$[/size]e^sinxcosx dx.
Solution:
[size=40]$[/size]e^sinxcosx dx
mere looking shows that sin will strike out cos and vice versa, but one is in power, i.e if you pick cos, you will have -sin, there is no "mathematical magic" that can strike out e^sin with sin, not just possible.
We will pick what as u?
.
.
.
.
.
.
Very good
u = sinx
dx = du/cosx
[size=40]$[/size]e^ucosx du/cosx
[size=40]$[/size]e^udu
hope you can still remember e is a standard integral?
e^u + c
e^sinx + c
. . . . . . . . . . . . . . . . . . . . . . . .
Summary:
Whenever you come across product of two functions:
1. The first thing is? Can one strike out the other after differentiation? If yes, . . . . . .you know what to do.
2. If 1 above does not work, can I manipulate to strike out the other? If yes. . . . . . .you know what to do.
3. If 1 and 2 above fail me, what next? Can I go round?

A big Care must be taken

.
Note: Not all products require algebraic substitution method e.g [size=40]$[/size]x e^sinx dx, [size=40]$[/size]x sinx dx, in this case, another method is adopted, but concerning JAMB/POST, integration for products end here.
. . . . . . . . . . . . . . . . . . . . . . . .

Any question?
