f(x)=xa^x+ln[x+(x^2+a^2)^(1/2)],求f''(0)=f(x)=xa^x+ln[x+(x^2+a^2)^(1/2)],求f''(0)=f(x)=xa^x+ln[x+(x^2+a^

f(x)=xa^x+ln[x+(x^2+a^2)^(1/2)] ,求f'(0)=
f(x)=xa^x+ln[x+(x^2+a^2)^(1/2)] ,求f'(0)=

f(x)=xa^x+ln[x+(x^2+a^2)^(1/2)] ,求f'(0)=
f'(x)=a^x+xe^xln(a)+[1+x(x^2+a^2)^(-1/2)]/[x+(x^2+a^2)^(1/2)]
f'(0)=1+0+1/a=1+1/a

f'(0)=1

(2a+3)/2

1+1/a
