The topic this quantity is specific integration, that's, the analytical in preference to the numerical resolution, of all types of nonlinear differential equations (ordinary differential, partial differential, finite difference). Such equations describe many actual phenomena, their analytic recommendations (particular suggestions, first necessary, etc) are in lots of circumstances most popular to numerical computation, that could be lengthy, expensive and, worst, topic to numerical error.

Example text

At the time of the observation, the comet was observable to the naked eye at 4th magnitude. By using 10 × 50 binoculars, I was able to see a thin ion tail and a wide dust tail. This tutorial will demonstrate the use of a preprinted star chart that will serve as a stellar framework for the sketch. Step 1: Framing and preparing the sketch area If you are preparing your preprinted star background using planetarium software, there are a couple things to consider. 1 appear or where the tail will be pointed, you may want to print a few sheets of the region at different scales and positions and bring them all with you.

There are no definitive answers on what type of paper you should use, and you should experiment to see which you prefer. Finally, you will want to consider how you want to store and protect your finished sketches. Some astronomical sketchers keep their work indexed and stored in vertical fi le folders, flat fi les, or plastic sleeves. Others keep their sketches in 3-ring binders or in pre-bound sketch books. The archival possibilities are numerous. Whatever method you use, you may wish to apply a spray fi xative to your sketches to help protect them from smudging and scuffing.

8) You may need to slip a narrow item such as an empty cassette tape holder beneath the clipboard so that the gooseneck clip has a thicker surface on which to attach itself. Another lighting solution that some amateur astronomers find useful and convenient is a red LED headlamp. A headlamp can keep your hands free, and point the light right where you need it. However, keep in mind that even a headlamp with adjustable brightness settings may still be too bright at its dimmest setting. If you find this to be the case, judicious application of masking tape, or electrical tape with small holes in it may help dim the light down to a manageable level.
