int(-5*10^(1/2)*(3+2*x)^2/(160*x^6+240*x^5-400*x^4-200*x^3+8*x^3*5^(1/2)*((4*x^2-28*x+29)*(-1+2*x+4*x^2)^2)^(1/2)+24*x^2*5^(1/2)*((4*x^2-28*x+29)*(-1+2*x+4*x^2)^2)^(1/2)+840*x^2+560*x+18*x*5^(1/2)*((4*x^2-28*x+29)*(-1+2*x+4*x^2)^2)^(1/2)+3*5^(1/2)*((4*x^2-28*x+29)*(-1+2*x+4*x^2)^2)^(1/2))/((3+2*x)*(20*x^3-30*x^2+35+5^(1/2)*((4*x^2-28*x+29)*(-1+2*x+4*x^2)^2)^(1/2)))^(1/2),x)
其中规定x = -1.5 .. -1/4-(1/4)*sqrt(5),求得是定积分
恳请各位仁兄帮忙,不胜感激。
