cos²a + sin²a = 1
Cos(a + b)
=
cos a * cos b - sin a * sin b
Cos(a - b)
=
cos a * cos b + sin a * sin b
Sin(a + b)
=
sin a * cos b + cos a * sin b
Sin(a - b)
=
sin a * cos b - cos a * sin b
tan(a + b)
=
tan a + tan b / 1 - tan a * tan b
tan(a - b)
=
tan a - tan b / 1 + tan a * tan b
cosinusregel: a²
=
b² + c² - 2bc * cos a
Cosinusregel: b²
=
a² + c² - 2ac * cos b
Cosinusregel: c²
=
a² + b² - 2ab * cos c
