thanks bro.

I just looked at your post and basically the same thing I think.

My method seems right too right?

well it said expanding so i expanded and got Sum(a^2)+ 2Sum(ab) Then i used a^2+b^2> 2ab and b^2+c^2>2bc ...... you add these 3 to get 2sum(a^2)> 2sum (ab) Then you get 3a^2+3b^2+c^2<1 since (a+b +c)=1 Then you do a>b>c and then you get it.

Dw I did similar for other questions in mc

Orite

Dw bro. Ur good. What do u think you got /100?

pi/4 was theta, I think

Same.

cos didn't see limits till after test. I don't have glasses but didn't see till after test.

Same I got stuck. But last minute I thought of using. Not enough time

Yeh I swear that was in the exam.

So what about using the velocity counterpart differentiation? Btw I didnt use the method using sin and cos in the test cos I though it was shifty. Damn wrong decision.

And btw whats the theorem called when a value for eg: 0^- < x < 0^+ and then you assume at lim n-> infinity x->0

oh btw did you guys do this for the increasing function proof : https://www.dropbox.com/s/2jkzl266d28huaj/2014-10-22%2015.27.02.jpg?dl=0 and can we prove that the function is increasing for the velocity counterpart in part i) to prove it is increasing?

easy. Dont worry you will be fine. And I dont think that you will get that anyways. Kostadalianas, stop scurrying around. How did you go?

Hm,.... emilios? Curious

Maybe. Actually now that I think about it. They were both same difficulty. So shouldn't be that much different.

This year probably 98 raw. Easier than last year as per my opinion.

Hey man. Thats great. Hope you can get yeh,
