SQT Stupid Question Thread

You'd have to use the complex log function because regular logs aren't defined for negative values.

the person posted it is having basic algebra problems and i'll wager that he/she doesn't know complex numbers

Then what sort of hypothesis might you form about the problem?

either the poster or whoever assigned the question wrote something down wrong

The system can be generated by choosing any two distinct (λ,μ) pairs
λ=1,μ=0 => ax+by+c=0
λ=0,μ=1 => a'x+b'y+c'=0
Solving for x and y gives you x0 and y0

m can be found by equating coefficients
λ(ax+by+c)+μ(a'x+b'y+c') = 0
=> (λa+μa')x+(λb+μb')y+(λc+μc') = 0

(y-y0)=m(x-x0)
=> y - m.x + (m.x0-y0) = 0

Note that both equations are homogeneous so you can multiply both sides by an arbitrary factor k.
=> k.y - k.m.x + k.m.x0 - k.y0 = 0

=> (λa+μa')x+(λb+μb')y+(λc+μc') = ky-kmx+(kmx0-ky0)

(λa+μa') = -k.m
(λb+μb') = k
=> m=-(λa+μa')/(λb+μb')

>people acting like complex numbers are somehow higher mathematics
Jesus fuck it's just an i. Imagine you asked your friend how to solve 2x=3 and he told you you can't possibly be expected to solve this because no one can expect you to know what rational numbers are.

when a lunar eclipse happens on earth does a solar eclipse happens on the moon at the same time? if yes it has even been observed?

That is indeed a stupid question.

I still don't know how to decipher it.
