nilai dari tan240°-tan210=

tan 240°-tan210°=
[tex] \sqrt{3} - \frac{ \sqrt{3} }{3} = 2 \frac{ \sqrt{3} }{3} [/tex]
semoga membantu

Tangen 240 = tangen (180 + 60 ) = tangen 60(nilai tangen + di kuadran ke 3)
Tangen 210 = tangen (180 +30 ) = tangen 30 (nilai tangen + di kuadran ke 3)

Jadi, tg 240 - tg 210 = tg 60 - tg 30 = sin 60/ cos 60 - sin 30/ cos 30
=(1/2 akar 3) / (1/2) - (1/2) / (1/2 akar 3)
=(3/4 - 1/4) / (1/4 akar 3)
=(2/4) / (1/4 akar 3)
= 2 / akar 3..dirasionalkan
Jadi, 2/3 akar 3
