Here are some easy ways to fix your cos-1 domain error.

Find $ cos (X) equal to 4/7 $ in quadrant IV (Cartesian plane)

However, I know the internet domain is limited to inverse cosine if you need to go to quadrants I and II. So, are there any strategies on how to answer the real question? there is no decision? Thank you for your time. Please let me know if I need to address a specific issue in any way.

## What is the restricted domain of cosine?

The constraint imposed on the world values of the cosine function is usually 0 ≤ x π (see Fig. 2). This limited role is called cosine.

## Why is inverse cosine an error?

The same is true for making sure you are inverting the cosine: cos is an error, so no real number has a good cosine of 2. However, tan can be any input value, that is – that is, any real number that you can imagine. from. Is a representation that has a tangent in the market that corresponds to this real number. This is just one of these definitions that requires because of the unity of the circle.

Then be careful$$ cos theta = cos (- theta) = cos varphi means frac47 $$Moreover, the angle of the first quadrant for me with $ theta $ satisfies$$ theta = arccos left ( frac47 right) $$So only the angle of the fourth quadrant has the same cosine, so it becomes $ 4/7 $, $ – theta $. If a person wants one that satisfies all inequalities $ 0 leq x <2 pi $, then the rate$$ x = varphi matches 2 pi - theta = 2 pi to arccos left ( frac47 right) $$

## Why does my calculator Say domain error?

ERROR: DOMAIN is often displayed when performing regression on a dataset, when the data being used probably does not fit the model for that particular regression type. The error indicates that they look the same: 1) There is an answer, it is outside the calculator selection.
