2x-0.24=1.
2x-0.24=1.
2x-0.24=1.
2x=1.2+0.24
2x=1.44
x=0.72
2x=1.2+0.24
2x=1.44
x=1.44/2
x=0.72
2x=1.44
x=0.72
X=(1.2+0.24)/2
=0.72
2x-0.24=1.2
2x=1.44
x=0.72
1.用公式计算:COSX=1-X*X/2!X*X*X*X/4!-X*X*X*X*X*X/6!.直到最后一项的绝对
已知x=2π+1.求(X-1)+(X-2)+(X-3)+(X-4)+(X-5)+(X-6)+(X-7)+(X-8)+(X-9)+(X-10)
1.x/9+x=62.x/x+1 + x+1/2x = 3
f(x)+f[(x-1)/x]=2x x不等于0,1.求f(x).
2x-0.24=1.
1.(1/X-1 )-2=X^-3X/X^-12.(X/X+1)^+5(X/X+1)+6=03.(8(X^+2X)/X^-1)+ 3(X^-1)/X^+2x
已知f(x)=x-1,g(x)={x-1.x≥0;2-x,x
化简求值:1/x(x+1)+1/(x+)(x+2)+.1/(x+2005)(x+2006),其中X=1.
不要检验!1.x+1/x-1 - 3x-3/x+1 = 22.7/x^2+x + 3/x^2-x = 6/x^2-1
1.(x-y)(x+y)+(x-y)+(x+y)2.x(x+2)-(x+1)(x-1),其中x=-二分之一请写清步骤,结果.
f(x)=x^2+x (x
1.(x*2-3x+3)/(x*2-3x+2)-(x*2-5x+7)/(x*2-5x+6)-1/(x*2-4x+3)2.1/x(x+1)+2/(x+1)(x+3)+3/(x+3)(x+6) 3.已知:x*2-3x+1=0,求x*2+1/x*2.
解方程 1.X/0.24=2.4 2.3X+2.7-0.9=7.89 3.9.2X+0.8X=108 4.2.5X+48=17.5
x/2(根号3x-根号2x)=-1.
1.f(x)=x^2+2ax-1 (x
因式分解f(x)=x^6+2x^3+1.
1.求f(x)={x^2+1,x
下列式子求导1.f(x)=x^3-3x^2+3x-22.g(x)=-3x^3+5x^2-4x+113.u(x)=-x^3+27x+74.h(x)=42-45x-3x^2+3x^35.f(x)=Lnx+x6.g(x)=x/(2+x^2)
