Answer 1

sin0° =0,cos0° =1,tan0° =0
sin30° =1/2,cos30° =√3/2,tan30° =√3/3
sin37° =0.602,cos37° =0.799,tan37° =0.754
sin45° =√2/2,cos45° =√2/2,tan45° =1
sin53° =0.799,cos53° =0.602,tan53°=0.754
sin60° =√3/2,cos60° =1/2,tan60° =√3
sin90° =1,cos90° =0,tan90° 无意义
sin120° =√3/2,cos120° =-1/2,tan120° =-√3
sin135° =√2/2,cos135° =-√2/2,tan135° =-1
sin150° =1/2,cos150° =-√3/2,tan150° =-√3/3
sin180° =0,cos180° =-1,tan180° =0
