Coefficients use for assessment of various aspects and also for calculations. Coefficients are necessary for correction of primary values therefore it is necessary to consider coefficients attentively and precisely.

Instruction
1. Define in what sphere of knowledge the coefficient which you need to count is used. Within this science find the corresponding subject and a formula on which the required calculation is made. Take a formula only on good authority, for example, from the textbook by the authoritative expert in the field or the official site of academy of Sciences. Manuals often supplement, update and republish. Therefore pay attention, information found you is how relevant, check sources.
2. Look on a formula what data are necessary for finding of coefficient. Write out their values. If you have not all data, calculate missing components of a formula by means of the calculator, papers and handles. For finding of some data you will need to find formulas of their calculation at first. Perhaps, to substitute data in a formula, it is necessary to carry out not computing, but measuring actions. Then the corresponding measuring devices will be necessary for you. For measurement use devices according to their appointment and record the received values on paper.
3. Consider provided in the found recommendation sources when calculating that calculations were as it is possible more precisely. For example, if it is necessary to take data for a certain period, do not vary time independently. Follow the rules, and you minimize quantity of mistakes and level of an error.
4. When all data standing in a formula are found, you pass directly to calculation of the necessary coefficient on a formula. Use for this purpose the calculator, the handle or a pencil and paper. Substitute in a formula instead of alphabetic references obtained dismissed and carry out. Compare the found number to standards if for your coefficient there is a recommended value or theoretically sufficient.
