即,cos120度 = cos(180度 - 60度) = -cos60度。查表或根据三角函数的基本知识,我们知道cos60度 = 1/2,所以cos120度 = -1/2。 English Answer: We know that cos120 degrees is an angle in the second quadrant, where the cosine value is negative. We can use the property of trigonometric fu...
Value of Cos 120 degree can be calculated using other trigonometric angles 90 degrees and 180 degrees. These cosine values can be gained from the trigonometric table.
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 t...

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...
