| Mar 22, 2022 at 15:36 | comment | added | Ulrich Neumann | @user64494 The same old story over and over again... By the way I didn't mention wether my answer shows the complete solution | |
| Mar 22, 2022 at 15:29 | comment | added | user64494 | @UlrichNemann: If you admitted in your answer that the plot in your answer draws only a part of the solution set, I didn't do my downvote. However, you didn't it. | |

-1. RegionPlot3D[ Cos[a] Cos[b] >= Cos[t - a] Cos[b] && Cos[a] Cos[b] >= Cos[t/2] && Cos[a] Cos[b] >= Sin[t/2] && a <= t <= Pi, {a, -Pi, Pi}, {t, -Pi, Pi}, {b, -Pi, Pi}, AxesLabel -> {a, t, b}] shows a bigger region.

Why {b, -1, 1} and {a, -Pi/2, Pi}?
