Q1) (b)

Evaluate limx0xex-log1+xx2

Now,

    limx0xex-log1+xx2          00 type and applying L'Ho¨spital's Rule

    Note that, ddxxex=xex+ex    and    ddxlog1+x=11+x

    =limx0xex+ex-11+x2x        00 type and applying L'Ho¨spital's Rule

    Note that, ddx11+x=-11+x2

    =limx0xex+ex+ex+11+x22

    =0e0+e0+e0+11+022          Substituting limit of x

    =0+1+1+12

    =32
