This is sort of unrelated but this thread might still be the best place to post it:
Yesterday's maths test went considerably well.
At first I somehow blanked out and forgot part of the basic derivation rules and didn't know if v' of f(x)=(3-x)*e^(x-1) would be (-1), (x-1) or 1, and I never really realised how that thing with +∞, -∞ and +0 works before; although a classmate briefly showed me before the test which exponentiations of e draw what sort of curves, but I almost immediately forgot that again, not to mention I never really internalised it anyway.
Well, I was sitting there unable to solve the first two of the three tasks due to those two flaws and already panicked that I would fail and get a bad grade and thus be unworthy etc... Until I then remembered my new doctrine of that I must not desire anything, similar to a Buddhist, and thus I calmed myself down, stopped caring and put on a calm smile.
And voilà, suddenly after testing a few things in the first task I saw that v'=1 was the only possible option and solved the problem, and thereupon the result of that task lead me to the realisation of how the thing with the curves of e^(+x) and e^(-x) works and thus I could also easily solve the second task!
In the end, I cleared 5/7 of all given (sub-)tasks very relaxedly and felt good. Shedding all worldly cravings is truly the right thing for me in life, even if I still haven't perfected it.
(Also guessing and then figuring out how things work by myself due to lack of preparation, haha.)
If anyone's interested, the graph I got for f(x)=(3-x)*e^(x-1) crossed the y-axis at (0|1.1) and the x-axis at (3|0), reached its highest point at (2|2.72), had its turning point at (1|2), and went towards +0 to the left and -∞ on the right, I hope this is all correct.
