Calc 2 FIrst Test

My very first test in calculus 2 I got ALL the answers right by that I mean, I did the "rocket science." I worked through all the formulas, did all the substitutions, and had the right symbols but let me back and fill in some preliminaries for ya.

CALCULUS 1 is mostly algebraic manipulation of integration and differentiation (inverses of each other) of various equations (formulations) that describe a rule or observation. For instance, k=ma describes the stretchiness of a spring, What is called kinetic energy or G=ma**2 is the formula for gravity.

By the way, k=ma and g=ma**2 is a form of Einstiens e=mc**2 famous equation! ?

CALCULUS 2 is CALCULUS 1 but with TRIGONOMETRY. trig when you do an integration, the answer changes the "SIGN" from postive to negative.
The two main "identites" are:
SIN integrates /evalutes to to -COS(x) + C NEGATIVE
and
COS integrates to SIN(x) + C
Dont forget the "+ C" part either, tem are points off too, arggggggg
Anyway I had them reversed for every problem, as every problem was trigonomic based, so this fucker gives me an "F" because I had the SIGN of each reversed.

I just forgot which was which was which and he gave me an F. can you believe it?
When I tried to argue with him, you know what he said to me? We don't build "upside down" bridges!!!!

I said, I am not building any bridges, everything I build is digital, 0's and 1's so to me, its just bullshit math

He didn't even give me any credit, not anything. I was so mad, but what could I do...!!!!

One good thing that came out of it was, I NEVER, NEVER made THAT mistake again!
