>How much Trig is in Calc I?
Not a whole bunch. So long as you have taken a pre-calc course you should be fine. Calc 2 on the other hand has a lot of trig, generally speaking.

If you're completely oblivious to calculus and your alegebra is so-so you it might serve you better to take calc 1 first, albeit the calc isnt that rigorous. But if your algebra is on point you could get by taking the two together.
>>
>>8418663
>Why do Americans need an entire university class on trigonometry anyway?

I have never heard of a school offering Trig as a seperate course in my school district in the US but i have heard about it before. I think it was originally a secondary track for those not able to do pre-calc and calc. Algebra 2 covers trig very briefly and in pre-calc you really get the full trig treatment. So, for those not taking pre-calc learning trig is really helpful for real world application.

By the first rotation, it wasn't a fermion anymore, by the second rotation it turned back into one. How about throwing a knife, what are the chances the pointy end will hit the wall?

>A fermion needed two full rotations, 720 degrees to come back into phase.
Think of fermions as being connected to the world with thin invisible ribbons that cant pass thru each other. rotating the fermion 360deg will give those ribbons a twist. This twist cant be undone unless you rotate the fermion back. Now rotate the fermion 720deg, the double twists in the ribbons can now be undone without any rotations.

Follow this gif and you can see how it goes back to its original state...
