目前这个反余弦函数计算器不能直接将结果转换为度分秒的形式。不过你可以手动进行转换。首先,将反余弦计算得到的弧度值转换为角度值,公式是角度 = 弧度 × (180 / π)。得到角度值后,整数部分就是度数,将小数部分乘以 60,得到的整数部分就是分数,再将新的小数部分乘以 60 就得到秒数。例如,计算得到的角度值是...
对于cos120度的三角函数值,我们可以利用三角函数的性质进行计算。以下是详细的解答: 中文解答: 我们知道,cos(180度 - α) = -cosα。因此,cos120度可以转化为cos(180度 - 60度),即-cos60度。 由于cos60度的值为1/2,所以cos120度的值为-1/2。 英文解答: We know that cos(180 degrees - α) = -...

The value of sin, cos, and tan of some angles are equal to the values of sin, cos, and tan of other angles. Let us take an example of cos(-30⁰). Since 30 degrees lie in the first quadrant we can say that cos(-30⁰) is equal to cos(30⁰) because all the angles in ...
