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

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

Let [x] denote the greatest integer not exceeding x. If l_(1) = lim_(x rarr 2^(+)) (x^(2) + [x]), l_(2) = lim_(x rarr 2^(+)) (2x - [x]) and l_(3) = lim_(x rarr (pi)/(2))((cos x)/(x-(pi)/(2))) , then

lim_(x rarr(pi)/(2))(cot x-cos x)/(pi-2x) equals: (1)(1)/(8)(2)(1)/(4)(3)(1)/(24)(4)(1)/(16)

Lim_(x rarr(pi)/(2))(e^(cos x)-1)/((pi)/(2)-x)

lim_(x rarr(pi)/(2))(cos x)^(cos x) is

lim_(x rarr(pi)/(2))(cot x-cos x)/((pi-2x)^(3)) equals

lim_(x rarr((pi)/(2)))(cos ecx-1)/(cot^(2)x) equals

Evaluate: lim_(x rarr(pi)/(2))(1+cos2x)/((pi-2x)^(2))

lim_(x rarr pi/2) (cotx-cos x)/(pi-2x)^3 equals :
