hey guys im wondering whats the answer for (1-4i)z=10+11i if i need z's imaginary part?
Not doing your homework nigger
it was on my exam but i dont know how to do it, can you help me brah?

>can you help me brah?
yes
>>7788878
will you please?
>>7788862
divide both sides by 1-4i and take the imaginary part
>>7788881
No.
>>7788888
Holy shit check those bodacious quints
>>7788888
>>7788881
Just divide both sides by (1-4i)
>>7788862
divide both sides by (1-4i)
multiply by the complex conjuage (1+4i)
simplify and take the imaginary term
>>7788862
[math] (1-4i)z = 10+11i [/math]
[math] z = \frac{10+11i}{1-4i} [/math]
[math] z = \frac{(10+11i)(1+4i)}{(1-4i)(1+4i)} [/math]
[math] z = \frac{-34}{17} + \frac{51}{17}i = -2 + 3i[/math]
[math] Im(z) = 3i [/math]

Technically, isn't the imaginary part simply 3? Don't we only cite the coefficient of the imaginary unit as the imaginary component of a complex number?
