\(0 = -2060,1 + 19631,77 \cdot \sin(α) + 39263,54 \cdot \cos(α) \cdot \frac{1}{2} \)
\( 19631,77 \cdot \sin(α) +19631,77 \cdot \cos(α) =2060,1\)
\( \sin(α) +cos(α) =0,105\)
\( cos(α) =±\sqrt{1-sin^2(α)}\)
\( \sin(α) ±\sqrt{1-sin^2(α)} =0,105\)
\( ±\sqrt{1-sin^2(α)} =0,105-\sin(α) | ^{2}\)
\( 1-\sin^2(α) =0,011025-0,21\sin(α)+\sin^2(α) \)
\( 2\sin^2(α)-0,21\sin(α) =0,988975\)
