Arccos definition

arccos(x) = cos-1(x)

 

For example, If the cosine of 60° is 0.5:

cos(60°) = 0.5

Then the arccos of 0.5 is 60°:

arccos(0.5) = cos-1(0.5) = 60°

Examinations of reasonable numbers. On the off chance that the indications of the looked at numbers are changed, at that point we can promptly say which number is more noteworthy and which is littler, so at the earliest reference point we will inspect the standard for contrasting levelheaded numbers and various signs. Further we will stop on examination of zero with other sane number. After this, we will harp on the correlation of positive sane numbers. At last, we continue to the standard of contrasting negative objective numbers. The hypothesis will be weakened with arrangements of trademark models.
