si 159/100 =a,bc

解答

s i \frac{159}{100} = a, b c

a = 0, s = 0

求解步骤

s i \frac{159}{100} = a

将

s i \frac{159}{100}

改写成标准复数形式:

0 + \frac{159 s}{100} i

0 + \frac{159 s}{100} i = a

将

a

改写成标准复数形式:

a + 0 i

0 + \frac{159 s}{100} i = a + 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 = a \frac{159 s}{100} = 0]

[0 = a \frac{159 s}{100} = 0] : a = 0, s = 0

a = 0, s = 0

6 i - 2 j = a (i - j) + b (i + j)

so l v e f or z, ba rz = i z

z^{2} = 1 - i

(x + 1) + 6 y i = 7 + 18 i

i z^{2} + 2 z + 8 - i = 0
