Materi : Trigonometri
Dalam Kuadran 1 ( + all )
sin A = 3/5 => tan A = ¾
sin B = 12/13 => tan B = 12/5
_____________________/
( tan A - tan B )/( 1 - tan A . tan B )
= ( ¾ - 12/5 )/( 1 - ¾ . 12/5 )
= ( 15/20 - 48/20 )/( 1 - 9/5 )
= ( - 33/20 )/( - 4/5 )
= 33/20 . 5/4
= 33/4 . ¼
= 33/16
= 2 + 1/16
Semoga bisa membantu
