Question

tg. x= radical de 3
x aparține (0,90⁰)
sin x=?
cos x=?
ctg x=?​

Answer 1

Răspuns:

Explicație pas cu pas:

x = 60°

sin 60° = √3/2

cos 60° = 1/2

ctg 60° = 1/√3

Answer 2

$\it x\in(0,\ \ 90^o),\ \ \ tgx=\sqrt3\ \Rightarrow x=60^o\\ \\ sinx=sin60^o=\dfrac{\sqrt3}{2};\ \ \ cosx=cos60^o=\dfrac{1}{2};\ \ \ ctgx=\dfrac{1}{tgx}=\dfrac{^{\sqrt3)}1}{\ \ \sqrt3}=\dfrac{\sqrt3}{3}$
