x+(3/4-3/10)=19/20
C语言求解方程x+x^2+x^3+x^4+...+x^19+x^20=41.6
x-10=4(x-28) 3(x-28)=x+56+28 2(1.5x-30-20)=x 2(2x-20-45)=x-1
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
4x-3x(20-x)=5x-7x(20-x)
4x-3x(20-x)=5x-7x(20-x)的解法
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
20+4x=6x-24 3(3x-2)=10-0.5(x-3.5)
1x()+2x()+3x()+4x()+5x()+6x()+7x()+8x()加9x()+10x()=1980
1X?+2X?+3X?+4X?+5X?+6X?+7X?+8X?+9X?+10X?=1980求?是多少
C语言中编写s=1-x+(x*x)/2!-(x*x*x)/3!+(x*x*x*x)/4!知道最后一项的绝对值小于10的-
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
