正弦值角度对照表公式如下:

0° (0弧度)

sin0° = 0

30° (π/6弧度)

sin30° = 1/2

cos30° = √3/2

tan30° = √3/3

45° (π/4弧度)

sin45° = √2/2

cos45° = √2/2

tan45° = 1

60° (π/3弧度)

sin60° = √3/2

cos60° = 1/2

tan60° = √3

90° (π/2弧度)

sin90° = 1

cos90° = 0

tan90° = 无定义 (正切值在此角度下趋于无穷大)

120° (2π/3弧度)

sin120° = √3/2

cos120° = 1/2

tan120° = √3

135° (3π/4弧度)

sin135° = √2/2

cos135° = √2/2

tan135° = 1

150° (5π/6弧度)

sin150° = 1/2

cos150° = √3/2

tan150° = √3/3

180° (π弧度)

sin180° = 0

cos180° = 1

tan180° = 0

210° (7π/6弧度)

sin210° = 1/2

cos210° = √3/2

tan210° = √3/3

225° (5π/4弧度)

sin225° = √2/2

这些公式可以帮助你快速查找和计算不同角度的正弦值。对于其他角度,可以使用正弦和角公式和差角公式进行计算:

sin(α+β) = sinαcosβ + cosαsinβ

sin(α-β) = sinαcosβ - cosαsinβ

希望这些信息对你有所帮助。
