indicated partial derivatives

The order of a differential equation is equal to the highest derivative in the equation. The single-quote indicates differentiation. So x ' is a first derivative, while x '' is a second derivative. x ' = 1/ x is first-order. x '' = - x..

It is a derived parameter to indicate how many people would be added to population. It also indicates the level of health care available to children and their mothers. Usually life expectancy at birth is higher than at later peri..

Holoparasites are those organisms, which are dependent upon their host for their entire nutritional requirement. Example: Cuscuta a total parasite of Acacia On the other hand, hemiparasites (or semi parasites) derive only a part of nourishment (usually water and minerals) from their host..

The degree of a differential equation is the highest power of the highest order derivative after making the equation free from radicals and fractional indices as far as the derivatives are concerned. In other words, the degree of a differential equation whose terms ar..

: diol Dihydric alcohols called as glycols or alkanediols are the dihydroxy derivatives of alkanes. In an alkanediol (dihydric alcohols) the two -OH groups are attached to different carbon atoms. The common and IUPAC names of dihydric alcohols are obtained as follows. The common name of..

Acids, bases and salts are three main categories of chemical compounds. These have certain definite properties which distinguish one class from the other. The sour taste of many fruits and vegetables, lemon for instance, is due to various types of acids present in them. The digestive fluids of mos..

1) Destruction of wild life leads to loss of valuable materials. 2) Disappearance of any link in a food chain upsets nature's balance and creates problems. 3) New improved varieties of crops and other useful animals are derived from their wild relatives by genetic modification. This ..

1. Both are operations on functions. 2. Both are linear. This is because of the following: (i) (ii) The constant can be taken outside the differential as well as integral sign as shown below: 3. We heve already seen that not all functions are differentiable. Similarly, all functions are not integra..

The term 'natural resources' refers to all the natural things on our earth. It includes everything, that is naturally available and that is not creatable by any human activity. It specifically excludes the materials created by man. Human being and his anthropological history indicate that..

Acidic substances generate H + ions in the medium, while basic ones liberate OH - ions in the medium Certain dyes are used as indicators to detect the presence of acids and bases Strength of an acid depends on the concentration of hydronium ions present in a solution. Greater th..
