The Casimiroa is a native of the Mexican highlands and as a result is fairly hardy. It has been recorded as surviving temperatures as low as -5 degrees Celsius.Rutacea-same family as citrus fruit, it is reputed to be one of the heaviest bearing of all fruiting trees, although this depends on variety selection.he Casimiroa is a native of the Mexican highlands and as a result is fairly hardy.

The scales provide the tangent or cotangent of the meridian altitude. In the last equations [sigma] = ds is the scalar arc element for (P) and (P'); [lambda] is cotangent angle, i. From 40[degrees] to 50[degrees], cotangent is a decreasing function.
These functions are the inverse of the cosine, sine, and tangent, respectively. To calculate these additional functions where angle is the measure of the angle in radians, use the following formulas: For example, to find the cotangent of a 30 degree angle, use the following formula:
