    $\begingroup$ "bcos" is an abbreviation, not a typo. What's wrong with "angle"? - my spell checker seems to be satisfied with it... $\endgroup$ – KeyboardWielder Apr 30 '16 at 19:55

    $\begingroup$ When the gates of heaven are opening, isn't there an angle between them? $\endgroup$ – KeyboardWielder Apr 30 '16 at 20:02

I'll take a go at it and say it's

The Imaginary Unit.

my reasoning:

do u know y i exists? bcos i is that that does not exist

i is something that does not exist

in plane terms i wanders : y is i

This seems like something related to plotting on a coordinate plane: In the complex plane, the y-axis is the imaginary axis representing i -- the imaginary unit.

sum1 and i in a relationship: it's complicated

Now it definitely is a mathematical quantity. and when we add 1 + i we get something "complex": a complex number! so we can confirm that i is the imaginary unit.

at times i is in heaven with an angle

i can be in the exponent of e with an angle, say $ \theta $ to get $ e^{i\theta} $

&& other times on the ground −− bless i, 4 i has sin

i appears on the ground when we use Euler's formula to rewrite $ e^{i\theta} $ as $ cos\theta + isin\theta $

    $\begingroup$ Correct! The topic was the symbol/unit in general (which exists for the purpose of denoting things that don't exist), and not specifically the formula. $\endgroup$ – KeyboardWielder Apr 30 '16 at 20:27
