书[1][2]收录了Wilkins的三个奇特结果:对任意△ABC(其内角A,B,C)有Ⅰ.sinAsinBsinC2≤293.仅当A=B=arccos133时取等号;Ⅱ.sinA2sinB2sinC≤154(213-5)·213+22,仅当A=B=a...
The book [1][2] includes three strange results of Wilkins: for any △ABC (with its inner angle A, B, C), I. sinAsinBsinC2≤293. Only take the equal sign when A=B=arccos133; II. sinA2sinB2sinC≤154(213-5)·213+22, only if A=B=a...
