Nonsense

and hide ya socks.....pixies steal socks :whee::wow::whee::wow:

cos 3x = cos 2x+x = cos 2x cos x - sin 2x sin x
= (cos2x - sin2x) cos x - (2 sin x cos x) sin x
= cos3x - sin2x cos x - 2 sin2x cos x
= cos3x - 3sin2x cos x


You can't possibly get more nonsense-ical than that. :rofl:

Well that's what i'm fighting now, while listening to "Take A Chance On Me" :laugh:


......


2 sin a sin b = cos (a-b) - cos (a+b)

Brainy pixies or sines/cosines with wings.

Math. Bleh.

You never use that stuff.

Apparently you also need it for programming. Which is another form of nonsense. For example:

#include<iostream.h>
#include<conio.h>


void main ()
{ float ma;
clrscr();
int n,v[100],s=0,i;
cout<<"N= ";
cin>>n;
for (i=1;i<=n;i++)
{
cout<<"v["<<i<<"]= ";
cin>>v[i];
cout<<endl;
}
for (i=1;i<=n;i++)
s=s+v[i];
ma=(float)s/n;
cout<<"Arithmetic average = "<<ma;
getch();
}

Don't remind me about programming. :cry:
