Im even more impressed by how fast you're changing from marker to marker😭😭

[zacharymcguirk]

Please questions on bearings or harder trig identities!

[ghost_-wr]

This is the basics for vectors as well

[jeremyncrm]

Freaking trig, every time I think I’m getting it some new thing comes along and upends it

[sammygamzz]

Bro that is quick to change the markers

Law of sine:

a/sinA = b/sinB = c/sinC = 2R

[Bob_qu]

Does a necessarily have to be the longest side or can any side be any letter?

[catalinac]

Scrieți și pentru b și a:
b^2=a^2+c^2-2ac cosB
a^2 =b^2+c^2+2bc cosA

[Свердлово]

wow, that's, like, school stuff, amazing

[neitoxotien]

Thats cool, is there a Law of Tangent?

[itz_phenorbx]

If it right angle cosC = 0 yeah C= π/2

[rcmfjones]

You probably also have one of those colorblind test shirts that says... Nothing I assume.

[botond]

😅Sine A over sine B is also equal to A over B😅

[adityamanohar]

The sine ratios are actually equal to 2R!!!!

[mariadelcarmenorihuelasant]

El seno de un ángulo es igual al coseno de su complemento.😅
