Matematika hitunglah sin (60°) tan (30°)+cosec 30° cotan 45° ​

hitunglah sin (60°) tan (30°)+cosec 30° cotan 45° ​

Penjelasan dengan langkah-langkah:

sin 60 = 3/2

Tan 30= sin 30/ cos 30

sin 30= 1/2

cos 30= 3/2

maka Tan 30 1/2×2/3= 1/3

cosec = 1/ cos

= 1/3/2= 2/3

cotan 45 = 1/Tan 45

Tan 45 = 1

maka cotan 45 = 1/1= 1

maka 3/2×1/3+2/3.1

= 1/2+ 2/3

= 1/2+ 23/3

=( 3+23)/6
