lim_(x rarr pi)(1+cos x)/(x-pi)

Lim_(x rarr pi/2)(cos x)/((pi)/(2)-x)

Evaluate the following limit : lim_(x rarr pi/2)(1+cos2x)/(pi-2x)^2 .

Evaluate the following limit : lim_(x rarr pi//2)(cos x)/(pi/2-x) .

lim_(x rarr pi) (sin x)/(x - pi) is

lim_ (x rarr pi) (1 + cos x) / ((pi-x) ^ (2))

lim_ (x rarr pi) (1 + cos x) / (tan ^ (2) x)

lim_ (x rarr pi) ((1 + cos x) / (tan ^ (2) x))

lim_(x rarr0)(cos x)/(pi-x)

Evaluate lim_(x rarr 0) (cos x)/(pi - x)

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
