Question

The value of lim x— 1 cos(pi/2 .x)/1- root under x

Answer 1

Answer:

π is final answer . for more answers follow me.

Answer 2

Step-by-step explanation:

lim cos(π/2x) / (1- √x)

0/0 form then apply D-L hospitalization rule :

lim (-sin π/2x)*(-π/2x^2) / (-1/2)(x^ -1/2)

at x = 1

lim (-1)*(-π/2) / (-1/2)

= (π/2) / (-1/2)

= -π
