`(lim)_(x->pi/2)(tan2x)/(x-pi/2)`

lim_( x to (pi/(2)) (tan2x)/(x-(pi)/(2))

lim_(x rarr(pi)/(2))(tan2x)/(x-(pi)/(2))

For alpha>0, let lim_(x rarr pi)(tan2x)/(x-pi)=lim_(x rarr0)((1-cos2 alpha x)^(2))/(x^(4)) then alpha is equal to

(lim)_(x->oo)((2tan^(-1)x)/pi)^x

Which of the following are true? lim_(x->pi/2+) tan x=oo , lim_(x->pi/2-) tanx=oo , lim_(x->pi/2) tanx=oo , lim_(x->pi/2) tanx=does not exist

(lim)_(x->1)(1-x)tan((pix)/2)\ a. pi/2 b. pi c. 2/pi d. 0

lim_ (x rarr (pi) / (2)) (tan2x) / (x- (pi) / (2))

Evaluate: (lim)_(x rarr(pi)/(2))((pi)/(2)-x)tan x
