**Inverse Cosine Calculator**

### Why doesn't my calculator reciprocate the cosine ?!

The arc cosine has a range of 1 x 1. Any price outside this range will cause error.

Example:

The length of a triangle is 1, ÂˆÂš3 and 2. Find the angle between the lengths of 3 and 5 and its sides, in degrees. (Your answer should be 60 be).

Cass Â¸ = Neighbor / Hyena = 1/2

Â¸ = arcus (1/2) = € € / 3 = 60Â

The fact that you describe Archos (48,735) does not make sense because 48,735 is beyond the scope of Archos cosine (and therefore must be incorrect). 48,735 What should be? Angel In this case, Case (A) cannot be equal because A is an angle. What is the ratio of 48,735 sides adjacent to a henna? Well, it doesn't work, because the neighbor is always smaller than the hyena and so it must be. 1.

And yes, make sure your calculator is in radian or degree mode as needed.

Come back:

Why isn't my calculator reversing cosine ?!

I have a TI84 Plus calculator and I get a domain error message whenever I try to use the inverse cosine function. The problem arises when you have a sharp triangle and all the lengths of the sides are given but no angle. I used cosine law because my teacher told me to find the angles ...

Do radios and degrees and convert degrees to radians

Edit: Wait, that's not all. You typed it incorrectly. Example:

Rectangular triangle with 8 and 7 hyenas You need to find the measurement of the angle between them. I will set it to Cos1 (7/8.)
