EVILFOREST:
..... and LATER some people will call EGYPTIANS, AFRICANS....
These are not Africans
They are not.
I keep saying that...
We share nothing in common apart from GEOGRAPHICAL LOCATION which was created by the Mediterranean Sea which separated them from their EUROPEAN and ARAB BROTHERS.

No CRUDE OIL yet see things for yourself.
EGYPT generates the Highest MEGAWATT of Electricity in Africa.
Yet no Crude Oil.

Are we not CURSED..?
BLACKS should start redirecting their Energy towards finding out whether the curse we are suffering from Is a COLLABO from both GOD and Devil together.

Egyptian names of the old days: Amenhotep, Imhotep, Amen-Ra, seth, Moshe, Ramses etc.

Egyptian names we have now: Salman, Muhammad, Khalid, etc.

What does this mean to you??

internationalman:
Hypocrite... In all your time in life can you swear you haven't done anything illegally to make money before...

Even if you haven't, would you have rejected if huspuppi offered to buy you a house and a car?? Just for instance oh.

We only criticize what we don't do or benefit from in this country..

Most people will do worse than politicians if the had the chance.

This kind of comment basically justifies the crime being criticized.

No one's a saint, but that doesn't mean you shouldn't criticise an action you know is morally wrong.

Not everyone is greedy (like you) and I mean it when i say not everyone would accept help from people who they know got their wealth illegally.

There is so much wrong with us in this country and one of it is refusing to stand up for what is morally right because we feel it won't fill our pockets.

Education › Re: Basic Mathematics Give Away by 8:00pm Monday 10th August by physicistman(m): 11:19pm On Aug 08, 2020

Integrating by parts
set u=x² and dv=sin2x
int x²sin2x = uv - int v du
du= 2x

v= -cos2x/2

int x²sin2x = -x²cos2x/2 - int -2xcos2x/2 dx
int x²sin2x = -x²cos2x/2 + int xcos2x dx

integrating xcos2x by parts again

u= x dv= cos2x
du=1 v= sin2x/2

int xcos2x = xsin2x/2 - int sin2x × 1 dx

int xcos2x = xsin2x/2 - int sin2x dx
int xcos2x = xsin2x/2 + cos2x/2

Therefore,

int x²sin2x= -x²cos2x/2 + xsin2x/2 + cos2x/2 + C

Final answer.
You are welcome sir.

Ugaboy:
For advance calcus
int x^2.sin2x
