Suppose `!+A` is non-singular. Let `B=(l+A)^(-1)` and C=l-A, then ……. (where l,A,O are identity, square and null matrices of order n respectively)A. BC=CBB. BC=OC. BC=lD. none of these |

Answer» Correct Answer - B We have `0lt(sinx)/(x)lt1" "("for "0 ltx lt 1)` `therefore" "0lt(sin x)/(sqrt(x))lt sqrt(x)` `I=underset(0)overset(1)(int)(sinx)/(sqrt(x))dxltunderset(0)overset(1)(int)sqrt(x).dx=(2)/(3)` Also `(cosx)/(sqrt(x))lt(1)/(sqrt(x))` `therefore J=underset(0)overset(1)(int)(cosx)/(sqrt(x))dxltunderset(0)overset(1)(int)(1)/(sqrt(x))dx=2`. |
