A = Intersect(yAxis, xAxis)
B_1 = (4, 0)
B' = Rotate(B_1, 29.999999999999996°, A)
α = Angle(B_1, A, B')
a_2 = Ray(A, B')
b = 10 (slider from 2 to 10, step 0.5)
c = Circle(A, b)
C = Intersect(c, a_2)
b_1 = OrthogonalLine(C, xAxis)
B = Intersect(b_1, xAxis)
Vieleck1, Ankathete, Gegenkathete, Hypotenuse = Polygon(A, B, C)
Text1: "sin (30°) = \frac{ " + Gegenkathete + " }{ " + Hypotenuse + "} =0,5"
Text2: "cos(30°)= \frac{ " + Ankathete + " }{ " + Hypotenuse + "}≅0,9 "
Text3: "tan(30°)= \frac{ " + Gegenkathete + " }{" + Ankathete + " }≅0,6 "
