This is the thread for all Math problems and problems Math can cause.

I actually need a help with this one.

|z+i|+i*Im(z+i)=~(5)+2i

~ is square root.

Im is imaginary set.

I know I should replace z with a+bi, but I don't know what to replace Im with.

Im(z+i)= b+1

There is no need to substitute for a + bi, you can use the Z as an incognite and check results afterwards, but the math itself is right! :)

Yeah, I know mate, but since he said that he should substitute with a+bi, I figured that's what he has learned in class :)

I was just surprised I still remember calculus! :lol:

Yeah, he probably learned like that in class. But there are a lot of short cuts you can do when you dont substitute, so I usually find it awkward (but it is not wrong by any means).

Fuck it, I still will have calculous when I resume Uni next year! :cry:

My last calculus course was, I think, in the first semester of the second year. My last mathematics course was the semester after; it was numerical analysis ( :mouthclosed:). Which year are you in now?
