Question Regarding Cosine Limit in renderer.py

[johanna0626]

Hi,
Thank you for your excellent work. I have been utilizing it in my projects, particularly in computing sine and cosine values. However, in this line
you've set the limit for the cosine value to (-1000, 0). I'm curious about the rationale behind this decision, as typically, the range for cosine values is (-1, 1). If the cosine value falls below -1, it becomes mathematically invalid to compute the corresponding sine value.

Could you kindly shed some light on why the limit was set to (-1000, 0) instead of the standard (-1, 1)? Understanding this would greatly aid my comprehension and usage of your work.

Thank you very much for your time and consideration.
