若角A,B满足-π/2若角A,B满足-π/2若角A,B满足-π/2-3π/2你可以取极值,先令A=B,则2A-B=A=B,而-π/2然后令A=-π/2,B=π/2,则2A-B=-3π/2所以-3π/2

若角A,B满足-π/2
若角A,B满足-π/2

若角A,B满足-π/2
-3π/2<2A-B<π/2
你可以取极值,先令A=B,则2A-B=A=B,而-π/2然后令A=-π/2,B=π/2,则2A-B=-3π/2
所以-3π/2<2A-B<π/2

若角A,B满足-π/2 若角A、B满足-π/2 若角A、B满足-π/2 若角a,b满足-π/2 若角a,b满足-π/2 若角A、B满足-π/2 若角A、B满足-π/2 若角A,B满足-π/2 若角A、B满足-π/2 若角A.B满足-π/2-π/2- 若角a,b满足-∏/2 若角a,b满足-派/2 若角a,b满足-90 若角a,β 满足 -π/2 已知a,b满足-派/2 设a,b满足-(pai/2) a,b满足0 a,b满足0
