A function is a relation.
Let:

[math]f_{1}\subset \{0\}\times\{0\}=\{(0,0)\}[/math] or [math]f_{1}:\{0\}\rightarrow \{0\}[/math].
[math]f_{2}\subset \{0\}\times\{0,1\}=\{(0,0),(0,1)\}[/math] or [math]f_{2}:\{0\}\rightarrow \{0,1\}[/math].
[math]f_{1}(0)=0[/math] so [math]f_{1}=\{(0,0)\}[/math].
[math]f_{2}(0)=0[/math] so [math]f_{2}=\{(0,0)\}[/math].

So the the functions are equal despite being "defined" on different sets.
Can anyone clarify this?

You have a polynomial and exponential. That's a transcendent equation. Either expand the exponential in series up to second order, and use the quadratic formula, or you can solve the equation using graphical/numerical methods (a computer).

I'm going into a calc exam and they don't give us any formulas. What's your experience with cheat sheets? I'm thinking about writing the formulas down on rice paper so I can eat it if someone tries to catch me.

Couple weeks into calculus 1 now, doing well, already past the chain rule and beyond. Quotient rule was a joke. Product rule remains my specialty.
I ask my professor his thoughts on quantum mechanics and partial derivatives. He's impressed i know about the subject. We converse after class for some time, sharing mathematical insights; i can keep up. He tells me of great things ahead like series and laplacians. I tell him i already read about series on wikipedia. He is yet again impressed at my enthusiasm. What a joy it is to have your professor visibly brighten when he learns of your talents.
And now I sit here wondering what it must be like to be a brainlet, unable to engage your professor as an intellectual peer.
All of the deep conversations you people must miss out on because you aren't able to overcome the intellectual IQ barrier that stands in the way of your academic success... it's so sad.
My professor and I know each other on first name basis now, but i call him Dr. out of respect.
And yet here you brainlets sit, probably havent even made eye contact with yours out of fear that they will gauge your brainlet IQ levels.
A true shame, but just know it is because i was born special that i am special. I can't help being a genius, nor can my professor.
Two of a kind is two flocks in a bush.
