log((1+i sqrt(3))/(1-i sqrt(3)))

log((sqrt2-1)/(sqrt2+1))

Y=log(4/(sqrt(x+2)+sqrt(2-x)))

log_((sqrt(2)+1))(sqrt(2)-1)=

If y=log(x^(2)+sqrt(x^(4)-a^(4)))," then "y_(1)sqrt(x^(4)-a^(4))=

which of the following are positive and negative: (i) log _(sqrt(3))sqrt(2) (ii) log_(4)((sqrt(2)+1)/(sqrt(2)-1))

If I=int(sin x+sin^(3)x)/(cos2x)dx=P cos x+Q log|f(x)|+R then (a)P=(1)/(2),Q=-(3)/(4sqrt(2))(b)P=(1)/(4),Q=(1)/(sqrt(2)) (c) f(x)=(sqrt(2)cos x+1)/(sqrt(2)cos x-1)(d)f(x)=(sqrt(2)cos x-1)/(sqrt(2)cos x+1)

I=int(log(t+sqrt(1+t^(2))))/(sqrt(1+t^(2)))dt=(1)/(2)(g(t))^(2)+c then g(2) is (A) 2log(2+sqrt(5)) (B) log(2+sqrt(5))(C)(1)/(sqrt(5))log(2+sqrt(5))(D)(1)/(2)log(2+sqrt(5))

What is log(a+sqrt(a^(2)+1))+log((1)/(a+sqrt(a^(2)+1))) equal to?
