Sudut (90 - a)
sin (90 - a) = Cos a
Cos (90 - a) = sin a
tan (90 - a) = cot a

Sudut (90 + a)
sin (90 + a) = Cos a
Cos (90 + a) = - sin a
tan (90 + a) = - cot a

Sudut (180 - a)
sin (180 - a) = sin a
Cos (180 - a) = - Cos a
tan (180 - a) = - tan a

Sudut (180 + a)
sin (180+a) = -sina
Cos (180 + a) = - Cos a
tan (180 + a) = tan a

Sudut (270 - a)
sin (270 - a) = - Cos a
cos (270 - a) = - sin a
tan (270 - a) = ctg a

Sudut (270 + a)
sin (270 + a) = -cos a
cos (270 + a) = sin a
tan (270 + a) = - cot a

Sudut (360 - a)
sin (360 - a) = - sin a
Cos (360 - a) = Cos a
tan (360 - a) = - tan a

Sudut (360 + a)
sin (360 + a) = sin a
Cos (360 + a) = Cos a
tan (360 + a) = tan a

Sudut Negatif
