    The value of integral \[\int_{0}^{1}{{{e}^{{{x}^{2}}}}}dx\] lies in interval                 [CEE 1993]

    A)                 \[(0,\,\,1)\]        

    B)                 (\[-1,\,\,0)\]

    C)                 \[(1,\,\,e)\]       

    D)                 None of these

    Correct Answer: C

    Solution :

                    For \[0<x<1\], we have \[1<{{e}^{{{x}^{2}}}}<e\], so that \[\int_{0}^{1}{1dx<\int_{0}^{1}{{{e}^{{{x}^{2}}}}}dx<\int_{0}^{1}{e\,dx}\Rightarrow 1<\int_{0}^{1}{{{e}^{{{x}^{2}}}}dx<e.}}\]
