log tan(pi/4+x/2)

If x = log [ tan (pi/4 + theta/2 ) ] then cosh x =

" 4."lim_(x rarr0)(1)/(x)log(tan(pi/4-x))=

y = log sec(pi/4 + x/2), show that dy/dx=1/2tan(pi/4+x/2)

int(dx)/(cos x+sqrt(3)sin x) equals: (1)(1)/(2)log tan((x)/(2)+(pi)/(12))+c(1)/(2)log tan((x)/(2)-(pi)/(12))+c log tan ((x)/(2)+(pi)/(12))+cquad log tan((x)/(2)-(pi)/(12))+c

What is int_(0)^(pi) log (tan""(x)/(2)) dx equal to?

Solve: tan(pi/4+x)+tan(pi/4-x)=2

If y= log_e tan ((pi)/(4)+(x)/(2)) then tan h (y)/(2)=

lim_(xrarr0)ln(tan(pi/4+2x))/(sin3x)=?
