Sinus: sin(alpha)= Gegenkathete/ Hypotenuse
cos(alpha)= Ankathete/ Hypotenuse
tan(alpha)= Gegenkathete/ Ankathete
a/sin(alpha)= b/sin(beta) = c/ sin(gamma)
sin^2(alpha) + cos^2(alpha) = 1
sin(alpha)/ cos(alpha)= tan(alpha)
cos(alpha)/sin(alpha)= 1/tan(alpha)
Sin(360+ alpha)= sin(alpha)
Sin(90° - alpha)= cos(alpha)
a^2= b^2+ c^2 - 2*b*c* cos(alpha)
b^2= a^2+ c^2 -2*a*c* cos(beta)
