lim_(x rarr1-)(sqrt(pi)-sqrt(2sin^(-1)x))/(sqrt(1-x))

lim_(xrarr1^(-)) (sqrtpi-sqrt(2sin^-1x))/sqrt(1-x)= (A) sqrt(2/pi) (B) sqrt(pi/2) (C) 1/pi (D) sqrt(1/pi)

lim_(x rarr(-1)^(+))(sqrt(pi)-sqrt(cos^(-1)x))/(sqrt(x+1)) is equal to

lim_(x rarr1)(sqrt(x)+3)

lim_(x rarr-1)(sqrt(pi)-sqrt(arccos x))/(sqrt(x+1))

lim_(x rarr0)(sqrt(1-x)-sqrt(1-x^(2)))/(sqrt(1+x^(2))-sqrt(1+x))

lim_(x rarr1)(sqrt(x^(2)-1)+sqrt(x-1))/(sqrt(x^(2)-1))

lim_(x rarr0)(sqrt(1+x)-sqrt(1-x))/(sqrt(1+x^(2))-sqrt(1-x^(2))) equals

lim_(x rarr0)(sqrt(1+x^(2))-sqrt(1+x))/(sqrt(1+x^(3))-sqrt(1+x))

lim_(x rarr1)(13sqrt(x)-7sqrt(x))/(5sqrt(x)-3sqrt(x))
