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.
In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'.Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.ngles greater than 90Â°. In a right triangle, the two variable angles are always less than 90Â° (See Interior angles of a triangle). But we can in fact find the cosecant of any angle, no matter how large, and also the cosecant of negative angles. For more on this see Functions of large and negative angles.
