>Using Tau instead of Pi

I seriously hope you guys don't do this.

Let me summarise the story for you:

Tau is better. That way the angles come out nicer when you use SOHCAHTOA.

wow it's so good to hear someone say this.

Everyone seems to love it.. but it's just morons politicking their pathetic cosmetic trivialities all over the fucking place. I can't wait until they fucking shut up.

Tau is clearly better, but it's not a big enough deal, it's not important enough to actually make the switch. We have other 'wrong' conventions floating around and we get by.

But it does make more sense.

If you want to change a wrong convention, abolish the american system of units already. That's in more need.

Tau is super bitchy and completely arbitrary. It makes no Goddamn difference, people just feel the need to go into full-on autism mode about a full circle being 2pi radians.

You're the one getting butthurt about it. And if you'd read anything about it you'd see how it clearly does make a difference.

that thing confused the hell out of me in high school because it was so variable and nothing is really nailed down.. plus the meaning of the symbols was not clear either.. I was under the impression they were some number that would replace the word sin or w/e.. (which is have true.. the numbers are constants but it related to the angle)

this shallow teaching method pushed me away from trig for and I stayed away from it for 3 years.. I just came to understand it a month ago.. and in high school they do nothing to explain the origin of the sine wave as a point spinning around a circle viewed from the side, nor the concept of the unit circle (in which the side opposite angle X is exactly the length of that angle [in degrees]. they also only explained radians as a method of conversion on the calculator and not the concept behind it (the arc being equal length to the radius)...

srsly american high school is retarded. it makes me very disgusted but I feel bad for the teachers because they were pushed into a shallow teaching method because of time constants and need to align with testing.. in which case the best method is to teach students the quickest way to answer the questions even if the concepts are not filled out at all.. (I assume that are some of the driving forces that make american education like it is)..

sorry for the rant.

I know it's arbitrary, I'm saying that it's dumb for people to get bent out of shape over a change that doesn't make any real difference. Status quo bias on my part? Maybe.

>> No.3301846

>>3301827
I've read plenty. It makes measuring angles a bit more intuitive, and it also makes a few derivatives show up more clearly. That's about it. The benefits just aren't great enough to switch everything over to tau.

>> No.3301851

Have fun writing the area of the unit circle as tau/2

>> No.3301854

Anything that makes it easier to learn math is good for math. I am convinced it is simpler to use tau than pi when teaching what radians are. Otherwise continue your merry day.

OP of >>3301833 here
I don't use it. the idea of a point on a circle centered around the angle in question is much easier and lets my re-orient multiple times when needed. the asshat acronym method only works for right triangles and only works when you can orient relative to the right angle.. is that right? I really don't give a shit about that backwards as hell retard method.

>> No.3301951

Really don't give a shit, literally the only difference is whether you write 2π or τ. We have used pi for thousands of years, and we will continue because it isn't worth the upheaval. There are no benefits to using tau any other than "it looks better.. am i asspie enough yet?" 2pi looks nicer than tau anyway. Fuck you taufags.

>> No.3301952

>>3301893

Since it's so closely related to pi, some symbol based on pi might be good.

Perhaps 2pi
