exp（850）How do I solve this problem,

[ZEROS-L]

Hello Because of the following formula, For D33 ,when (xr+12) > 0, then yr>-∞,and that will cause the following solution to fail. For D11 when (xr+12) > 0,then yr<∞,and that will also cause the following solution to fail.How do I solve this problem, or how do I set limits

[svigerske]

To avoid that xr+12 > 0, setting the upper bound of variable xr to -12 or lower could help.

I'm sorry, I didn't make that clear, but xr can be greater than and less than 12, but when xr+12> 0, you get yr> -∞, this is beyond the scope of evaluation, what should I do about it

[ZEROS-L]

For example, when y>5000, the computer can recognize 5000, but. -∞, the computer can not calculate or recognize the -∞ boundary,

You may have to look into scaling your variables and equations such that values are in a reasonable range.

SO how to scale variables and equations

Hello, I have scaled the function, but a point with a denominator of 0 appears, causing the following problem, what should I do? Is there any way to initialize or set or ignore this zero point separately?
