The range of cosine is [-1, 1] which is, therefore, the domain of cos-1. As a result, cos-1(2) is not defined.
-2 is the additive inverse of +2
Mult. inverse of 2 is 1/2, mult inverse of 14 is 1/14, mult inverse of 214 is 1/214
To apply the law of cosines to find the measure of an interior angle in a triangle, you need to know the lengths of all three sides of the triangle. Specifically, if you have sides ( a ), ( b ), and ( c ), you can find the angle opposite to side ( c ) using the formula ( c^2 = a^2 + b^2 - 2ab \cos(C) ). From this equation, you can isolate ( \cos(C) ) and then use the inverse cosine function to determine the measure of angle ( C ).
.5 is 1/2 The inverse of 1/2 is 2
Additive Inverse would be the number that when added to a given number creates a total of zero. The additive inverse for any negative number would be the positive counterpart. The additive inverse of -5 is 5. The additive inverse of -2 is 2, since -2 + 2 = 0.

2 is the multiplicative inverse of 1/2 Therefore 2*1/2 = 1
The multiplicative inverse of a number is another number that, when multiplied together, results in 1. For 0.5, the multiplicative inverse is 2, since (0.5 \times 2 = 1). Therefore, the multiplicative inverse of 0.5 is 2.
The additive inverse of 8 2/5 is -8 2/5.
