#diff eqs

differentiation is and always has been, simply objectively better. there is NOTHING, absolutely not a single problem, where integration achieves something that could not be done by simply looking at a problem and knowing in your heart what differentiation was done to obtain it.

Hopefully, no one had the misfortune of taking this class, but just in case, I figured I should upload my study guide for this too. Hope it helps you poor souls who took this class! :)

Here’s Part 1: Basic Definitions/Operations. Part 2 in just a moment!

He is so beautiful. He is a genius. He is just casually being a genius. He's not even trying, he just does it. How does he think I'm smarter than him? I wonder if he knows I'm looking at him.

I'm good at math. The determinant is zero if you make the matrix upper triangle. Row reduction is so much better than cofactor expansion. That also means the matrix is singular, doesn't it? Math is so fun.

He's so attractive. He's just doing genius stuff. I wonder what it is. I wonder if he knows I'm watching.

Sal is annoying. He needs to leave me alone.

I like the boy's skin. It's nice. It has a good tone. I like that fold in his neck when he looks that way. I like his hands a lot. I like the hair on his chin a lot. I like that bump of his spine at the base of his neck. I like his chin hair so much. He has nice lips.

I wonder what he thinks of me. He probably thinks, "Wow, she's gorgeous." And "Wow, she's a genius." He probably thinks I'm beautiful. I think he likes me. I wonder if he knows I'm looking at him.

He has beautiful chin hair and like the curves of his face and it's smallness and he's so cute. I can imagine what he looks like when he's making love. I can imagine what he looks like when he's in love. I wonder what his insecurities are. I wonder what he thinks when he's alone and looks in the mirror. I wonder if how he looks matters to him.

Everyone is so rude putting all their stuff away early.

Sal is annoying and needs to leave me alone.
