sinA=0.4658 角A为多少 就这几个值求角的度数
sinB=0.8702 cosA=0.7129 cosB=0.0311 tanA=27.342 tanB=4.3798
再加上sin13度 和sin37.2度 的值

sin1=0.01745240643728351 sin2=0.03489949670250097 sin3=0.05233595624294383 sin4=0.0697564737441253 sin5=0.08715574274765816 sin6=0.10452846326765346 sin7=0.12186934340514747 sin8=0.13917310096006544 s...
