It's a neat idea, but does it have any noteworthy applications?

No. Scientists made it all up to keep women put of the high paying science field. Glass ceiling baby.

Check out the entire field of AC electronics and electrics.

If your lecturer wants to be a dick about mohrs circle

>>8477832
Why is the diagram so inaccurately drawn?
It looks like you don't know what a tangent is!

>>8477841
>don't have the unit circle memorised
What is there to memorise? It's a circle of radius 1.

>>8478980
this
lmfao

knowing it will make calculus way easier when you recognize an expression as the derivative/ integral of a trig function.

Also, trigonometry is used in navigation and surveying, though oddly that's with the functions they don't teach in most trig classes.

apparently somebody thought it would be useful to memorize a few points on the unit circle to do mental trig

>tangent not even at a right angle to the hypotenuse
mods pls

Were I to meet you, I would strike you dead for this

>>8478980
Yeah, It needs to be 90 dee

It did back in the day before computers now most ppl are to lazy to do anything with out their technology.

>>8480765
you do realize that tan(pi/3) is not 2, right?

>>8477841
3rd year of highschool is tough isnt it?

>>8477832
My fucking statics home work.....


Thanks, now i see why i should use tangent to find theta.


I needed this in my statics class work today to find a normal force that was at an angle.

FBD and other shit (two pins, one roller, and another roller at the angle)

>>8478980
he marked the angle saying its 90 degrees.
thats meaningfull enough to understand whats going on

Well maybe thats why it is called tangent...

>>8480882
the tangent value is the length of the AC segment, which is sqrt(3)...

>>8477832
this is absolutely USELESS

>>8477841
literally highschool, you can even memorize just what values are in it and reason out which goes where on the spot
