Sin (180° + α°) = -sin α°
Cos (180° + α°) = -cos α°
Tan (180° + α°) = tan α°
Cot (180° + α°) = cot α°
Sec(180° + α°) = -sec α°
Cosec (180° + α°) = -cosec α°
mau nanya ko yg sin, cos, sec itu minus tapi tan sama cotnya gak minus

ada contohnya gak kak?

tan210 = tan(180+30)
tan210 = tan30
tan210 = 1/akar 3
