in(in(inx))=y

解答

in (in (in x)) = y

解答

x = 0, y = 0

求解步骤

in (in (in x)) = y

化简

in (in (in x)) : - i n^{3} x

- i n^{3} x = y

将

- i n^{3} x

改写成标准复数形式:

0 - n^{3} x i

0 - n^{3} x i = y

将

y

改写成标准复数形式:

y + 0 i

0 - n^{3} x i = y + 0 i

复数仅在实部和虚部均相等时才相等改写为方程组:

[0 = y - n^{3} x = 0]

[0 = y - n^{3} x = 0] : x = 0, y = 0

x = 0, y = 0

流行的例子

(1+x)=(1+r)*(1+i)

(1 + x) = (1 + r) \cdot (1 + i)

x^{2} - 8 x i - 25 = 0

(x+iy)+2(x-iy)=(2i)/(1+3i)

(x + i y) + 2 (x - i y) = \frac{2 i}{1 + 3 i}

3 i y^{2} - y + 2 i = 0

x(1+i)^2+y(2-i)^2=3+10i

x (1 + i)^{2} + y (2 - i)^{2} = 3 + 10 i
