yeah. truth is x(t) = Ae^((+ or - )t) + 2npi - pi/2 when you take this into consideration. plugging it back in, you do get the equation to work still (even for the + case)
Neat differential equation! But how about “x = cos x”? The result is an irrational (and even transcendent!) number that might be worth a mention on your channel. :D
Ich habe versucht, den Trick aus diesem Video zu wiederholen, und jetzt habe ich einen neuen Rekord aufgestellt - viel Gelächter und ein kleines Desaster💝
does anyone remember the dvd logo bouncing around the screen
Yes, it also changed colour while bouncing.
Who doesn't? And the times when it hits the corner!!
nice video... love the advent calendar series
Since the solution to cos(x)=y is x=(+ or -)arccos(y)+2*pi*k, I'm thinking you need a 'plus or minus' in front of the -x-pi/2.

Nearly got through the Advent Calender! Keep up the work!
5:14 how come you can cancel the dt's?
It’s the opposite of the chain rule:
df/dt = df/dx•dx/dt
You can look up “Integration by substitution” on Wikipedia. It contains a complete proof.
Proven the shit!

already done :)
How about integral sin(dx)
very early
