Trig is crazy math..

Trig you have degrees. Now what if the value in degrees equals some Measurement
For example. If you were to look at the slope of a mountain from bottom to top you end up with so many degrees. A mountain climber will look at degrees and say to self WFT? How many feet is that from bottom to top.

That's weird notation that I've never seen before. All it means is that any given angle ß (greek letter beta) is a sum of some other angle α (alpha) plus any multiple of 360°. k is any integer (..., -3, -2, -1, 0, 1, 2, 3, ...). α is best and simplest to be limited to between 0 and 360.
For example, 865 = 145 + 360*2

I'm guessing the m is for modulus? It's just a formula for doing mod(360) math.
@OP
You're just wrapping numbers around like you do on a clock. On a clock you're doing mod(12) math because the counting system has an upper limit of twelve. Here you're doing the same but with 360 as a max value of degrees. Remember that thing you wrote to convert wait times from raw minutes into hours or whatever? You were using the same kind of modular arithmetic formula there but with mod(60) to convert minutes. It's kind of the same deal.

K means degrees Kelvin. It's like Celsius but it starts at absolute zero. So 360°K means it's 360 degrees Celsius above absolute zero (zero in Celsius is the freezing point of water).
360°K=86.85°C

maybe but who the fuck teaches modulus shit in an introductory trig unit

They just mentioned this because of the book, right now, they just said that m(α) and m(ß) are coterminal. I presume they want us to think of them as just variables at this current point in the course.

I was just trying to find a rationale for writing the notation that way. They probably should have described it clearly and sensibly like you did.

yeah I wanted to bitch out the book authors in any case

Right now, this is pretty straightforward. The tutor even said that it is though it is complicated for someone who is first learning it.
