The purpose of checking a proof on inequalities is to ensure that the mathematical argument presented is logically sound and all statements and steps are valid. This helps to avoid errors and confirm the accuracy of the proof.
To check a proof on inequalities, you should carefully read through each step of the proof and verify that it follows the rules of mathematical logic. You should also check the validity of any assumptions or definitions used in the proof.
Some common mistakes to look out for when checking a proof on inequalities include incorrect application of mathematical properties, incorrect use of symbols or notation, and circular reasoning.
While a calculator can be useful for numerical calculations, it should not be used to check the validity of a proof on inequalities. This is because a proof relies on logical reasoning and not just numerical values.
If you find an error in your proof on inequalities, you should carefully review your steps and identify where the mistake was made. Then, correct the error and recheck your proof to ensure its validity.
