Il Limite di log(2sen^2x-senx) con x che tende a π/6 da destra si può fare a mano o ci vuole la calcolatrice?

Lim log(?x +1)/ log(x+1) = f.i. X->+oo lim log? X( 1 +1/?

X)/ logx(1+1/x) x->+oo lim log? X+log( 1 +1/? X)/ logx+ log(1+1/x) x->+oo lim log x½+log( 1 +1/?

X)/ logx+ log(1+1/x) x->+oo lim (1/2)log x+log( 1 +1/? X)/ logx+ log(1+1/x) x->+oo Dividi numeratore e denominatore per logx ---- lim (1/2)+log( 1 +1/? X)/logx/ 1+ log(1+1/x)/logx = (1/2)/1 = 1/2 x->+oo.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
