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.
The arctan function is the inverse of the tangent function. It returns the angle whose tangent is a given number. Try this Drag any vertex of the triangle and see how the angle C is calculated using the arctan() function. For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arctan button may be labelled atan, or sometimes tan-1.) So the inverse of tan is arctan etc.
