Avoid Loss of Significance in Function: Tips & Advice

In summary, Loss of Significance in Function refers to the loss of accuracy or precision in mathematical calculations due to rounding errors or limited-precision numbers. It can occur when using numbers with a large difference in magnitude or irrational numbers. To avoid this, alternative forms of equations, higher-precision numbers, and avoiding subtracting similar magnitude numbers can be helpful. It is important to avoid loss of significance in function as it can lead to inaccurate results and affect various fields such as science, engineering, and finance. It can also occur in different applications such as physical quantities, finance, data analysis, and computer programming, where it can affect the accuracy of results.

Well, I got this: tg(x) (cos(x) - 1).
Is that good enough? how can I check it?

Thanks a lot.
