if `L=lim_(x->pi) {tan(picos^2x)}/(x-pi)^2` then `L/pi` is equal to:

lim_(x->pi/4)(tan2(x-pi/4))/(x-pi/4)

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

The value of lim_(x to pi) (tan(picos^2 x))/(sin^2 x) is equal to

The value of lim_(x to pi) (tan(picos^2 x))/(sin^2 x) is equal to

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

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

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

Evalute lim_(xrarrpi/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
